example usage of vedic / fast maths.

lets see in what all ways the vedic maths or better say fast maths can be used to beat your own mental skills and in some cases, even calculator ;)

Example 1 : Finding Square of a number ending with 5
To find the square of 75

Do the following

Multiply 5 by 5 and put (5X5)=25 as your right part of answer.
=> xxxxxxx25
now,Multiply 7 with the next higher digit
=> 7 X (7+1)=7X8
gives 56 as the left part of the answer
so, Answer is 5625


Example 2 : Calculate 43 X 47 (The above 'rule' works when you multiply 2 numbers with units digits add upto 10 and tenth place same)
3X7=21

xxxxxxx21
4X(4+1)=20

The answer is 2021 Same theory worked here too.

same as above; Find 52 X 58 ? Answer = 3016 How long this take ?

Example 3: Multiply 52 X 11
answer is 572
Write down the number being multiplied
5xxxxxxxxx2
and put the total of the digits between two digits
52 X 11 is [ 5 and 5+2=7 and 2 ] ,
answer is 572
note: in case you want to multiply 52 with 111
just write 7 twice => 5772
in case of 1111
57772

sum,here 5+2 = 7 is written one time lesser than the 1's in the digit.

Answers # 6 to 10

question:6=> AB + CD = AAA, where AB and CD are two-digit numbers and AAA is a three digit number; A, B, C, and D are distinct positive integers. In the addition problem above, what is the value of C?

(A) 1

(B)3

(C) 7

(D) 9

(E) Cannot be determined
Ans: AB + CD = AAA

Since AB and CD are two digit numbers, then AAA must be 111

case even if ab and cd are the biggest numbers possible even than 96 + 87 = 183.

Therefore 1B + CD = 111

THATS WHY C=9, FOR ALL VALUES OF B.

PROOF: B can assume any value between 3 and 9

If B = 3, then CD = 111-13 = 98 and C = 9

If B = 9, then CD = 111-19 = 92 and C = 9

So for all B between 3 & 9, C = 9

Therefore the correct answer is D (C = 9)



QUESTION:7

1. A certain quantity of 40% solution is replaced with 25% solution such that the new concentration is 35%. What is the fraction of the solution that was replaced?

(A) 1/4

(B) 1/3

(C) 1/2

(D) 2/3

(E) ¾
Ans: Let X be the fraction of solution that is replaced.

Then X*25% + (1-X)*40% = 35%

Solving, you get X = 1/3


QUESTION:8

A bag contains 3 red, 4 black and 2 white balls. What is the probability of drawing a red and a white ball in two successive draws, each ball being put back after it is drawn?

(A) 2/27

(B) 1/9

(C) 1/3

(D) 4/27

(E) 2/9

Ans:

Case I: Red ball first and then white ball P1 = 3/9*2/9= 2/27

Case 2: White ball first and then red ballP2 = 2/9*3/9 = 2/27

Therefore total probability: p1 + p2 = 4/27



QUESTION:9

What is the least possible distance between a point on the circle x^2 + y^2 = 1 and a point on the line y = 3/4*x - 3?

A) 1.4

B) sqrt(2)

C) 1.7

D) sqrt(3)

E) 2.0

Ans:

The equation of the line will be 3x - 4y - 12 = 0.

This crosses the x and y axis at (0,-3) and (4,0)

The circle has the origin at the center and has a radius of 1 unit.

So it is closest to the given line when, a perpendicular is drawn to the line, which passes through the origin.This distance of the line from the origin is 12 / sqrt (9 + 16) which is 2.4
[Length of perpendicular from origin to line ax +by + c = 0 ismod (c / sqrt (a^2 + b^2))]
The radius is 1 unit.

So the shortest distance is 2.4 - 1 unit = 1.4 units



QUESTION:10


In the square above, 12w = 3x = 4y. What fractional part of the square is shaded?

A) 2/3

B) 14/25

C) 5/9

D) 11/25

E) 3/7

ANSWER:

Since 12w=3x=4y,

w:x=3:12=1:4 and x:y=4:3

so, w = 1x = 4y = 3

the fractional part of the square is shaded:

{(w+x)^2 - [(1/2)wx + (1/2)wx +(1/2)xy + (1/2)w(2w)]}/(w+x)^2

= {(w+x)^2 - [wx + (1/2)xy + w^2)]}/[(w+x)^2]=[(5^2) -(4+6+1)]/(5^2)

= (25 - 11)/25

= 14/25.

Question # 10

In the square above, 12w = 3x = 4y. What fractional part of the square is shaded?
A) 2/3
B) 14/25
C) 5/9
D) 11/25
E) 3/7

INTRODUCTION OF VEDIC MATHEMATICS

  • WHAT IS VEDIC MATHEMATICS?

It is an ancient technique, which simplifies multiplication, divisibility,squaring, cubing, square and cube roots.

Even recurring decimals and auxiliary fractions can be handled by Vedic mathematics. Vedic Mathematics forms part of Jyotish Shastra which is one of the six parts of Vedangas. The Jyotish Shastra or Astronomy is made up of three parts called Skandas. A Skanda means the big branch of a tree shooting out of the trunk.

AND THE BEST PART IS - you dont even need a calculator for this purpose.

  • What is the basis of Vedic Mathematics?

The basis of Vedic mathematics, are the 16 sutras, which attribute a set of qualities to a
number or a group of numbers. The ancient Hindu scientists (Rishis) of Bharat in 16 Sutras
(Phrases) and 120 words laid down simple steps for solving all mathematical problems in
easy to follow 2 or 3 steps.


Vedic Mental or one or two line methods can be used effectively for solving divisions, reciprocals, factorisation, HCF, squares and square roots, cubes and cube roots, algebraic
equations, multiple simultaneous equations, quadratic equations, cubic equations, biquadratic
equations, higher degree equations, differential calculus, Partial fractions,Integrations, Pythogorus theoram, Apollonius Theoram, Analytical Conics and so on.

Vedic Maths / Vaidic Maths / Vadic Maths (whatever you call)

we are restarting the series we stoped in middile. we posted a lesson about vedic maths for our readers as well but that wasn't carried on properly as well. so now we are starting again from the very begining and this time we will be going from the root of the technique known as
"VEDIC MATHS or VADIC MATHS or VAIDIC MATHS"

WHATEVER YOU CALL IT BUT ITS A BRILLIANT TECHNIQUE THAT CAN MAKE YOU DOUBT YOUR OWN MENTAL CAPABILITIES.

WE SUGGEST ALL READERS TO GO ONE BY ONE AND READ EACH POST VERY SERIOUSLY CAUSE EVERY THING IS RELATED TO EACH OTHER.

Question # 9

What is the least possible distance between a point on the circle x^2 + y^2 = 1 and a point on the line y = 3/4*x - 3?
A) 1.4
B) sqrt (2)
C) 1.7
D) sqrt (3)
E) 2.0

Question # 8 (simple probability)

A bag contains 3 red, 4 black and 2 white balls. What is the probability of drawing a red and a white ball in two successive draws, each ball being put back after it is drawn?
(A) 2/27
(B) 1/9
(C) 1/3
(D) 4/27

maths formule

we got a wordsheet that consists many useful formule. all formule are common but being together, makes really easy to revise.
first page i am posting right now.


GMAT FORMULAS
Summation Formula = (Number of numbers)/2 * (f + l), where number of numbers = f – l + 1

Percent Change = Difference/Original

Rectangular Solid Volume = L*W*H

Cube Volume = S*S*S

Cylinder Volume = PieRsquaredH

Surface Area (Combined area of all the surfaces, or faces, of a solid)

Surface Area of Rectangular Solid = 2lw + 2lh + 2wh

Surface Area of a Cube = 6ssquared

Principal + Interest = principal * (1+r)>t, where

Total = Group 1 + Group 2 – Both + Neither

Quadratics
• (x + y)2 = x2 + 2xy + y2
• (x – y)2 = x2 – 2xy + y2
• (x + y)(x – y) = x2 – y2

Number of permutations (different arrangements when order matters) = (n!)/(n-r)!

Number of combinations (arrangements when order doesn’t matter) = (n!)/r!(n-r)!

where n = number of objects in the source group
where r = number of objects selected

The length of a given side must be greater than the difference of the other two sides and less tha
the sum of the other two sides.

question #2 correction

guys and gals plz have a look

there is some typing error in question number 2.

actually i typed questions in ms word and pasted them here. which caused this error.

anyways its the correct question

The price of a bushel of corn is currently $3.20, and the price of a peck of wheat is $5.80. The price of corn is increasing at a constant rate of 5x cents per day while the price of wheat is decreasing at a constant rate of {[under root(x)] -x})cents per day. What is the approximate price when a bushel of corn costs the same amount as a peck of wheat?
(A) $4.50(B) $5.10(C) $5.30(D) $5.50(E) $5.60


explain the answer now cause its already answered.

Thursday, November 29, 2007

here are the answers of first 5 questions....

1. The sum of the even numbers between 1 and n is 79*80, where n is an odd number, then n=?

Sol:
First term a=2,
common difference d=2
since even numbertherefore sum to first n numbers of Arithmetic progression would be
x/2(2a+(x-1)d)
=> x/2(2*2+(x-1)*2)=x(x+1)
and this is equal to 79*80
therefore x=79 which is odd...
so number of even terms between 1 and n are 79.
means n= (1+2*79) =159


2. The price of a bushel of corn is currently $3.20, and the price of a peck of wheat is $5.80. The price of corn is increasing at a constant rate of 5x cents per day while the price of wheat is decreasing at a constant rate of cents per day. What is the approximate price when a bushel of corn costs the same amount as a peck of wheat?(A) $4.50(B) $5.10(C) $5.30(D) $5.50(E) $5.60

Soln:
320 + 5x = 580 - .41x; x = # of days after price is same;
solving for x; x is approximately 48,
thus the required price is 320 + 5 * 48 = 560
cents = $5.6

3. How many randomly assembled people do u need to have a better than 50% prob. that at least 1 of them was born in a leap year?

Soln:
Prob. of a randomly selected person to have NOT been born in a leap yr = 3/4Take 2 people,
probability that none of them was born in a leap = 3/4*3/4 = 9/16.
The probability at least one born in leap = 1- 9/16 = 7/16 < year =" 3/4*3/4*3/4" born =" 1" 64 =" 37/64"> 0.5
Thus min 3 people are needed.

4. In a basketball contest, players must make 10 free throws. Assuming a player has 90% chance of making each of his shots, how likely is it that he will make all of his first 10 shots?

Ans:
The probability of making all of his first 10 shots is given by(9/10)* (9/10)* (9/10)* (9/10)* (9/10)* (9/10)* (9/10)* (9/10)* (9/10)* (9/10) = (9/10)^10 = 0.348
=> 35%

5. A and B ran a race of 480 m. In the first heat, A gives B a head start of 48 m and beats him by 1/10th of a minute. In the second heat, A gives B a head start of 144 m and is beaten by 1/30th of a minute. What is B’s speed in m/s?(A) 12(B) 14(C) 16(D) 18(E) 20

Ans:
race 1 :- ta = tb-6 ( because A beats B by 6 sec)
race 2 :- Ta = tb+2 ( because A looses to B by 2 sec)
By the formula D= S * T
we get two equations
480/Sa = 432/Sb -6 ------------1)
480/Sa = 336/Sb +2------------2)
Equating these two equations we get
Sb = 12ta,
Sa stand for time taken by A and speed of A resp.

A and B ran a race of 480 m. In the first heat, A gives B a head start of 48 m and beats him by 1/10th of a minute. In the second heat, A gives B a head start of 144 m and is beaten by 1/30th of a minute. What is B’s speed in m/s?
(A) 12
(B) 14
(C) 16
(D) 18
(E) 20

test taking tips....sc

Sentence correction

About one-fifth of the sentences will be perfectly correct as is. If you read a sentence that sounds okay, it probably is. A tightly worded sentence is generally considered more effective, so, all things being equal, choose the shortest answer. In every case , you should base your answer on the conventions of standard written English. Do not fall into the error of using informal, conversational English as the criterion for answering sentence correction questions. In particular, sentence correction questions measure your knowledge of the following points of grammar:

1) agreement of the subject and verb.
2) parallel construction
3) agreement of pronoun and antecedent
4) correct use of adjectives and adverbs.
5) correct placement of modifiers.
6) coordination and subordination of sentence elements.
7) tense sequences.
use of correct case with prepositions.
9) correct diction (choice of words).
10) proper use of idiom.

practice meterial has been posted many times regarding this. the famaous guides sc section is sufficient for this.

SOME TEST TAKING STRATEGIES AND TIPS - RC

Reading comprehension

There are a number of different categories of GMAT reading comprehension questions; however, certain general solution procedures can be applied successfully to most or all of them. THE BETTER NAME FOR THESE SO CALLED PROCEEDURES IS THUMB RULE.

Here is one such procedure that many test takers find helpful.

Step 1: Skim over the questions quickly

Skim over the questions at the moderately fast rate. This quick inspection should help you determine which of the questions ask you about information directly stated in the passage, which ones call for the use of inference , which ones ask you to make evaluations, and so forth.
or you can simply say - try to use your brain only in those things which were asked for marks and leave everything else.
Once you have skimmed the questions, you should have some idea of what to look for as you read the passage. Make sure you skim the questions quickly! This is a preliminary step, so you should't spend too much time on it. You will be rereading the questions more carefully in a later step.

Step 2: Read the passage at your fastest rate.

Read the passage at your fastest rate-without skimming. You shouldn't worry about full comprehension of the passage at this point. The purpose of this step is to give you an idea of the structure of the passage and to familiarize you with the locations of keys words, facts, and ideas. As you read, try to keep in mind the questions you just skimmed. If you come across material that seems related to a question, remember the line number , then check that question's wording. Don't worry if at this point you can't recall all of the questions or if you can't find materials relating to all of the questions in the passage. You will see the questions and the passage again during the course of later steps.

Step 3: Reread the questions at your best rate for comprehension, and check the materials you found during your first reading of the passage in Step 2.

The purpose of this step is to enable you to answer the more accessible questions quickly so that you may concentrate on the more taxing questions during the next two steps.

Reread the questions one at a time. This time, as you read, do so at your best rate of reading for comprehension. After you have read a question, think back to the reading of the passage that you did in Step 2. If during that reading you noted materials that were relevant to the given question, find those materials again and reread them to see if they provide the answer. If they do indeed do so, mark the answer in the appropriate place.

If you come to a question for which you did not find any relevant materials when you read the passage, go on to the next question! Don't read the passage again to find answer material unless you are fairly sure that you know where that material is. If you have no idea where the answer material is located, reading the passage again to find it can cost you valuable time.

Step 4: Reread the passage at your best, most comfortable rate for comprehension.

Your purpose during this reading will be different from that of your first reading in Step 2. This time you will already be aware of the overall structure of the passage, so you can concentrate instead on finding subtler meanings. Also, by this time you should have fewer questions to think about since you have probably already answered several of them during Step 3.

This step will be your final complete reading of the passage. This time read the passage at your most comfortable rate for comprehension, but don't stop and backtrack at any point. As you read, keep in mind the questions that remain unanswered. Then follow the same process as in Step 2: if you come across material that seems related to a question, remember the line number , then check that question's wording. Resist the temptation to break off your reading and backtrack. Keep on reading!

Step 5: Reread the questions that are still unanswered and check the materials that you found when you reread the passage in Step 4.

This step calls for a third reading of the questions that you have not answered yet. Follow the same process as in Step 3. After you have read a question, think back to your rereading of the passage in Step 4. If during that rereading you noted materials that were relevant to the given question, find those materials again and check to see if they provide the answer.


BUT TO BE VERY FRANK.. "PRACTICE" IS THE "KEY"

test material

here is link of a good test regarding gmat. try this out....

filehostingsite.com - test link


do post your comments plz

work smart and not just hard...

ok guys. finally i am free and got all the data that i almost lost in my crashed harddisk.
any ways....
as clear by the subject of this particular post - to clear the test named gmat or cat or such others the main thing is to work smartly and mind shouldnt be closed from any field.

like i give you one example:-
a few tests back there was a question, particularly in quant section, looking very much as an equation but was rather a very simple mind-bender

question said- if two is 20-23-15 and seven is 19-5-22-5-14 then how will if write twenty seven and there were many options available.

i am quoting this particular question only because this question got maximum wrong attempts. and to be very frank and to the best of my knowledge, was a bit confusing as well.

confusing????? yes it was cause of one thing

the way mind work.... hard harder and ...............

some friends converted the alphabets t-20 means a-1, b-1, c-3 and so on to z-26 and did than tried to find out the similar options

but to the surprice there were 3 options very very similar to that and at the end all 3 were wrong

and the correct option was 20-23-25-19-5-22-5-14

simply 2 7 = 27


the moral is simple that while going through question dont start think hard from the very first second. give it a read and then try to hit the bull.

anyways we will keep posting these tricky things now onwards. you just keep preparing for the test coz its not too far now ;)


for study material thing i will mail all the readers the asked material now
vedic maths / vadic maths / vaidic maths lessons will be started from today only so keep reading...............

SORRY READERS

HEY READERS
its really a long time back we made any post and we are very sorry for that.
actually we were very stuck in something very important and were busy in sorting the issue out.
any ways we hope you will understand that. we will start uploading the lectures on vedic/vadic maths we have promised. arround 30 of them are waiting to be uploaded and practice by you people.

moreover we are about to start a forum for the site and the biggest thing to inform you is-

we are starting a sollution portal for our readers.
we have some 5 prof. joined with us for seprate subjects and they will be putting sollutions for your problems from di to quant

so feel free to ask as many problems as you have now

have a great fun

vedic matsh lesson - 2

Hello friends.How the preparation is is going. I am back with vedic maths lesson 2 as I promised in earlier post and I can say your wait for this post hasn’t got waste as this post will give a direct hint to what amazing power vedic maths has and why u need to master it.

I said in my first post that vedic maths is contained in 16 sutras and 16 sub sutras. Today in this post I shall start with the sutras.

I’m starting with the 2nd sutra of Vedic maths. The 1st will come a little later on.

SUTRA 2 – NIKHILAM NAVATAS’CARMAM DASATAH

(Simply meaning “all from 9 and the last from 10 “ )

This formula can be very very effectively applied to multiplication of numbers which are near to the bases like 10,100,100 ie to the power of 10’s.This formula is very simple and will make multiplication steps reduced to minimum and leave it all on very simple mental calculation. I bet after reading this post you will be able to do calculations like 997 x 990 in a matter of seconds maybe a minute at max and all yourself. So lets start.

The difference between number and base is called deviation. the deviation can be positive or negative. Negative deviation can also be written as bar n top of number but it’s not necessary.

Ex Number are 14. The deviation will be (14-10) = 4. We took base 10 here .Another example 96. The deviation here will be 3 (103-100). We took base 100 here.


Now lest start the multiplication . lets start with easy numbers like..

7 X 8

we will apply the nikhilam ( sutra 2) to do this now.

In this case the base is 10 for both the numbers.

Step 1-


Write both numbers to be multiplied one below the other like

7

8

Step 2 – take deviation from both numbers and write them in from of them like..

7 -3

8 -2

Step-3 answer

Now the answer will have the 2 parts . The right hand side and the left hand side. Don’t get confused here its all very simple in practical sense.

7 -3

8 -2

7-2/ (3X2) = 5/6=56

as you can see what I did was in the RHS of the answer we just multiply the deviations that is 2X3 in LHS(left hand side) of answer we can do 4 methods but the method I chose here was I subtracted the 2 from 7 ie I subtracted 2nd deviation(2) from 1st number (7) and we got 5 as RHS ( right-hand side) of answer, then we just combined the RHS and LHS of answer and we get 5 / 6 = 56




Lets do this for :-

98 X 97

98 - 02

97 – 03

98-3 / 3x2= 95/06 = 9506




Example –

994 X 988

994 - 006

988 -012

-------------------

994-12/ 6X12= 982/072 = 982072




1275 X 1004

1275 -275

1004 - 004

1279/275X4 = 1279/ 1_100 = 1280100 ( 1 got carries to RHS )




CASE - where one number is more and other is less than the base.


Example

13 x 7

13 - 3

7 - (-3)

13-03 / 3x3 = 10/-9 = 100-9 = 91

So that was the Sutra -2 . I know many of you may have doubts and question about this as it cannot be that simple. You can just leave a comment in the comments below with your questions and I will explain with example solutions.

Thank you

Vedic (vadic) maths – lesson 1

Vedic math or the ‘fast math’ is a system of reasoning and mathematical working based on ancient India teachings called Veda. It is fast efficient easy to learn and use.

It is being taught in some of the most prestigious institutions in the England and Europe. NASA applied its principals in the filed of artificial intelligence.

What is vadic maths?

It is an ancient technique which simplifies, multiplication, divisibility, complex numbers, squaring, cubing, and square and cube roots. Even recurring decimals and auxiliary fractions can be handled by vadic maths. Vedic math’s forms a part of the jyotish shastra which is one of the six parts of vedangas. The jyotish shastra or astronomy is made up of 3 parts called skandas, it mean big branch of tree shooting outwards.
Vedic maths was made famous by a swami called bharathikrishna (1184-1960)


Basis of vadic maths

The basis of vadic maths is 16 sutras, which attribute a set of qualities to a number or a group of numbers. The ancient Hindu scientist (rishis) of bharat (India) in 16 sutras (phrase) and 120 words laid down simple steps for solving all mathematical problems in easy to follow 2 or 3 steps.

Mental or 1 or 2 line Vedic methods can be used effectively for solving division, reciprocal, factorization , HCF , squared and square roots, cubes and cube roots, algebraic equations, multiple simultaneous equations, higher degree equations, differential calculus, partial fractions, integration, Pythagoras theorem , Apollonius theorem, analytical conics and so on.

Is it useful in today’s world?

Given the initial training of modern math to students in today’s school, students will be able to comprehend the logic and achieve unimaginable help in their working in the world afterwards. It is amazing how with the help of 16 sutras and 16 sub-sutras the vedic seers were able to mentally calculate complex mathematical problems.

Vedic maths is utmost important for every GMAT and CAT aspirant. It will give u a huge boost in your quant section as you will be able to do all the calculation mentally and with amazing fast speed. This saves time in your examination and increases your moral.

Now we all know what is vadic maths and it importance. In the next lesson we will start with the 16 sutras and how to apply the vadic math logic to mathematical problem.

vedic maths(vadic maths)- JUST MASTER THIS ART.

hello readers
first of all we want to appologise for the delay in supply of these lessons. actually the delay was the result of time consuming process of resolving copyrights. but finally we have 100% exclusive rights for the lessons we have prepared for our readers.

yes we are talking about the same 32 lessons that we promised to our readers regarding vedic maths. we have made these lessons with personal experience and expertise of many professors who are professional vedic/vadic maths lecturers.

for your interest and knowledge we, now, will be uploading each and every know-how we have by now regarding vedic maths for you on this online gmat prepration site.

we will start from tomorrow about how to go on with this trick and how to master this trick.

we will guide you exactly how i, personally, worked on this art and i am 100% sure that by the end of these lectures you will be able to solve those mathematical calculations oraly which you couldnt even think of doing before.

so here is the very first assignment for those who really want to master this trick.
first of all you have to learn tables.

plz dont think you know them even if you know them. this art becomes much more easy to catch up if you know the most basic thing in maths i.e. tables

you must be clear with tables from 1X30 to 30X30
though there is no fixed limit - the more you know -the better it will be for you.

there is no need for this file but still to make the path absolutely smooth we have uploaded this file containing tables that you must be loaded with.

note:- plz note we are not asking you to cram but just to read them on daily or twice a day so that slowly these will be on your tips. and this is not the first lesson but only the ice breaking exercise.

so here is the link to download

www.filehostingsite.com - tables 30X30

we will start with lessons in no time now
so be uptodate with these tables

VEDIC MATHS (VADIC MATHS).

FOR OUR READERS!

from 1 of may we will start a new section on vedic/vadic maths (whatever you call) and this will take around 32 lectures or you can say 32 posts to cover all those chapters. we have developed those 32 chapters with a detailed discussion with our professor. (discussed in olders posts as well) and this will help a lot in the test. you will be able to answer a lot faster and correct in quant that you can't imagine.

personaly! i am pretty sure that after going through those lessons and doing a littile practice, you will be able to master vedic maths.

so i suggest all the readers to take those lessons very seriously and keep practicing side by side. otherwise at the end of the day you will be having everything to learn at once.
so keep reading - keep learning - keep practicing ang then break the wall called gmat. :)

---------------------------------------------------------------------------

I SUGGEST ALL TO SUBSCRIBE TO THE BLOG IF YOU ARE NOT SUBSCRIBED ALREADY COZ THIS WILL ENABLE TO GET ALL THE UPDATES REGARDING THE NEW LESSONS AUTOMATICALLY ON YOUR EMAILS AND WE WON'T BE NEEDED TO POST THE SAME LESSONS AGAIN ON YOUR REQUESTS.

OG-11 AND LATEST NEWS ON ONLINE GMAT PREPRATIONS.

hey readers!
hope your preprations would be going fine.

many of our readers are searching for the og guide 11th edition. though we have provided the link long time and now its not on the first page and our readers find it difficult to find that so i am providing you the link again.

link 1 - rapidshare - OG-11
link 2 - esnips- 0G-11

--------------------------------------------------------------------------

FOR OUR READERS SPECIALLY NEW ONES-

many of our new readers were keen to know about how to start with the preprations. so i would like to tell you my friends what i believe in...." its always most difficult to start something. "
once you will start the thing it will become very very easy for you to go on with the thing and today we are going to discuss how you should start for the thing called "gmat"

mates its not difficult at all if you follow the correct path.
-to begin with the thing i would suggest you to start with time management. atleast 2 hours a day must be given by an average mind like me and most of others.
-the best thing is to divide time to study all portions of gmat like quant, sc and vocab and all coz all sections are equally important.
-though you will need to work harder on quant coz there is no fixed formula for that.
-for english portion - reading a few books on vocab and some excercises on sc will be sufficient but for quant you will need to work and work a lot.

i suggest those who are starting from now to start with the same and for quant and maths section plz read what i am going to tell next.

SENTENCE CORRECTION AND DATA SUFFICIENCY

hey readers!
hope your preprations are going well.

some of our readers are a bit confused about how much time is sufficient to prepare for the test and being and online gmat prepration blog we are supposed to know the answer but to be very frank and honest - there is no time line that can be drawn as a endline for the prepration.
and keep in mind that there is no starting line as well.

i can place a number of example where people cracked the gmat easily just with a study of 10-15 weeks and opposite to the list of these examples their is a list of those who prepared for long 2-3 years to get the desired results.

so we can not suggest any fixed time though we can tell you the average.

as per a survey conducted in USA, the average study of 20-26 months was sufficient for average people. [average people is used for the people who are scoring average grades in their past educational background]

SO I THINK YOU CAN NOW ESTIMATE TIME YOU WILL REQUIRE TO GET THE THINGS GOING IN DESIRED DIRECTION.

well i think its enogh of generalised topics and we should come back to some work. i mean we are a online gmat prepration and gmat study material providing blog and we shouldn't waste more of your time. so here is something useful-

since long time we havent discussed much of sentence correction. so here you can download this utility which explains the basics of sentence correction + show types of questions that are most likely to appear in test.

this file also include questions on data sufficiency.
[THOSE WHO HAVE DOWNLOADED THE OTHER FILE WE GAVE ON DATA SUFFICIENCY A DAY BEFORE YESTERDAY ARE NOT REQUIRED TO THAT EXCERCISE AGAIN]

WWW.FILEHOSTINGSITE.COM -- SC FILE + DATA SUFFICIENCY

that's what we have today as gmat study material. we will provide a great book tomorrow for which you are waiting for long.

from next week we will start providing some info about business schools in USA. this is the info we collected by visiting those schools and we will also try to provide you forms [those one which are generally need to be filled] so that our reader wont need to waste their time in useless search work.

thats what for today on online gmat prepration.

vocab through flash cards...

some of our friends were asking us to provide some flash cards to make sure that they will be able to go smoothly with their vocab.

for those who aren't that familiar with flash cards let me tell you what they are and how they could be helpful for you.

flashcard is a way of presenting the words in such a way that the similar meaning words are kept at one card and this makes it really to understand or you can say it makes it easy to figure out the meaning and relate from word to word.

you can learn more about vocab or flash cards more by downloading it.

here is the link

FLASH CARDS FOR VOCAB


MATES THIS IS A REQUEST.

-FOR THOSE WHO WANT US TO SEND THEM THE FILES LIKE OG-LL OR K-800 JUST SUBSCRIBE TO OUR BLOG COZ ITS VERY DIFFICULT FOR US TO PICK EACH AND EVERY EMAIL AND SEND THE FILE TO THE ADDRESS. BUT IF YOU SUBSCRIBE THEN IT WILL BE DONE AUTOMATICALY.

-LET US KNOW THE NAME OF THE RESOURCE AS SOON AS YOU KNOW ABOUT THAT AND THINK COULD BE USEFUL IN STUDY SO THAT BOTH YOU AND US COULD BE KEPT UPDATED.

lets do some vocab pracice...

hey mate!
vedic maths is good to learn and is really very useful in exams and we have to keep one thing is that after some practice we can solve almost all quesions regarding maths but what about vocab???

in this case, there are only two posibilities....
-either you know the answer
-or you dont...

and in reading comprehensions, the whole para could be clear in one reading or could demand many readings just if we dont have a good vocab.

so now we will work give a littile try to our vocab as well.

and unlike vedic maths it cant be tought coz there is no formula but yes we can give you a good base to start with.

so here is a file which have some good words to test where you stand right now.

A SMALL COLLECTION OF WORDS

we suggest you
-not to loose hope if you think you are not good enough coz its just need some practice and everything will be fine sooner than you can think of.
-reading news papers, magazines and novals are the best way to keep a good vocab.
-keep the new words in mind and try to make some sentences with them.
-the best way is -try to use them in day-to-day communication
-spelling should be focused as well.

OG-11 RESOURCE..

HEY FRIENDS!
some of our readers were asking about og-11 resource

so here is the link to download that.

OG-11

please let us know if you need or think any other utility should be provided or will be useful

VEDIC MATHS:- QUERY SOLVING

hey friends..

one of our regular readers asked us a question about some trick which can help in subtracting a number from the base number.
we are sorry for the delay in solving that query but that happened coz i was busy in my exams.

here is a trick which i think could be helpful...

step 1:- take the number you need to subtract from base number

(it will surely be near that number. i mean if you have 22 your base will be 100 or if its 760 then it might be 1000)

step 2:- subtract the units digit from 10, and remaining digits from 9 of the number you need to subtract from the base.

and thats it... :)

isnt it really simple

lets see it with an example

you want to subtract 638 from 1000 so what will you do....

6---3---8 (subtract from)
!----!----!
9---9---10
------------
3---6---2 is the answer
------------

you can subtract any number from base number with this trick




and one more thing friends
we will provide the link for OG-11 today with in 2 hours
the file is in uploading process

let us now if you need any other utility or resource.

keep working smart (not hard) :)

Some neat vedic math tricks

SQUARING OF NUMBERS NEAR THE BASE.

Observe simple examples:

97 Squared = 97 -­ 3 / 3x3 = 94 / 09
96 Squared = 96 -­ 4 / 4x4 = 92 / 16.

When the number being squared is above the base, of 100 here, we add the Excess and Square the Excess:
104 Squared = 104 + 4 / 4x4 = 108 / 16 = 10, 816
104 x 105 = 104 + 5 / 4x5 = 109 / 20 = 10, 920

What if we enlarged our numbers to 998 Squared?

It is close to 1,000 so we say Base 1,000 and know to have 3 zero's on the right hand side of the ( / ).
998 Squared = 998 -­ 2 / 2x2 = 996 / _ _ 4 = 996 / 004. = 996,004

Understanding this, you can be calculating digits in the millions: 9998 Squared = 9998 -­ 2 / 2x2 = 9996 / _ _ _ 4
(Since we are in Base 10,000 the 4 zeros determine the need for 4 digits after the ( / ). = 9996 / 0004 = 99,960,004.


THE SQUARING OF NUMBERS ENDING IN 5


If we wanted to square the number 25, ie 25 x 25, we would conventionally take 3 lines of working out. Vedic Mathematics merely looks at the Question, applys one of the 16 Sutras, and solves it Mentally in One-Line. In this case, the Sutra at work is "By One More Than The Previous Digit".

Observing that 25 is a 2 digit number, 5 is the last digit, but we are mainly interested in "the Previous Digit" which is 2.
We say, mentally, "What is One more than Two?" It is 3. The word "By" in the Sutra really means "to multiply".
The setting out for the first half of the answer is thus:
25 Squared = 2 "By" 3 / ........ = 2 x 3 / ........ To this we tag on the last digit "5" squared: = 2 x 3 / 5 x 5 = 6 / 25
Thus the answer is 625.

Similarly, all other numbers that end in 5, when squared, can be done instantly:
15 Squared = 1 x 2 / 5 x 5 = 2 / 25 = 225
35 Squared = 3 x 4 / 5 x 5 = 12 / 25 = 1,225
45 Squared = 4 x 5 / 5 x 5 = 20 / 25 = 2,025
95 Squared = 9 x 10 / 5 x 5 = 90 / 25 = 9, 025

VADIC MATHS - LESSON NUMBER TWO.

after learning how to square a number ending with 5 now we will do something called comman base method.

this method is a technique of multiplying number which comes under same base.
this base could be anything like
-10
-100
-1000 etc.

to multiply two numbers we just need to make them subtracted or added to a comman base.
lets do an example.
MULTIPLY 99 X 92

step 1:-MAKE COMMAN BASE
here the base is 100. (coz while setting the base we should keep in mind that the base should be closest to the numbers to make sure that the minimum calcultaions will be required.

step 2:-SUBTRACT THE NUMBERS FROM THE BASE AND WRITE THEM IN THE ORDER.

100- 99 = 01
100- 92 = 08
(we write the number we get after subtraction in as many digits as many zeros we have in the base, here we have 2 zeros in 100)
AND YOU HAVE TO WRITE THESE IN THE FOLLOWING SEQUENCE

99 01
X !
92 08
----------
91 08 = 9108 is the answer


this 91 we get my subtracting (92-01) or (99-08) cross digits
and 08 we get by multipling the straight line of the digits we get after subtraction from base (01 X 08)
the zero wil remain coz we have two digits in our base.

isnt it simple

now lets try this with two digits which
one is bigger than base another is smaller than base

112 X 92

so step 1:-
112-100 = +12 (no need to add zero coz we have only two zeros in base and we have two digits in 12 as well)
92-100 = -08 (the sign will be on negative coz 92 is lesser than 100)

(in the previous example we ignore negative sign by subtracting both the digits from 100 but in this case its not possible)

so now we have

112 +12
92 -08
-------------
104 -96

now we have to right it like this

10400
- 96
-----------
10304 thats the answer
-----------

you can try this on any number

try it

tables are still important

learn from 1X30 to 30X30

we will keep posting more tricks till then master these ones

VADIC MATHS - FIRST LESSON

after getting a good response about vadic maths here is the very first lesson about this.
before starting let me tell you again that its not gona be a cup of tea but yes, we can do this all together.

keeping in mind that "practice makes a man perfect and writting makes a man exact"
we will start our very first lesson.

ok the very first thing we will discuss is squaring a number ending with 5

ok let begin with this (you must be knowing that 5 square is 25 ) ;)

step one: take a number ending with 5.

say, 45.

step two: write the ten's and unit's number 25 without thinking much.

so you have xxxxx25 (doesnt matter how many digits before 25)

step three: take the remaining number before 5 from the original number

in this case its 4

step four: add 1 to this number(step 3) and multiply the number with the number of step three.

means (4+1) X 4 = 20

step 5 : simply put this number(step 4) in front of step 2's 25

means 20 25

and thats your answer 2025

you dont even need a calculator.

now we will try this formula for some more numbers...

lets take 25.....

----- xxxxx25
------ (2+1)X2 = 6
--------- 625

thats the square of 25 :)

lets do this for a bigger number say, 85

------- xxxxx25
------- (8+1)X8 = 72
------- 7225
thats the answer

you can use the same formula for ever number ending with 5.

and now the homework comes......

you should learn the tables.... i know you have done a lot of them in school but its time to revise them

learn from 1X20 to 30X20 or atleast till 20X20

this will help when you solve three and four digit numbers...

let us know if you like this lesson coz this lesson is just the begining and we will do many more

QUANT! ---- VADIC MATHS.

hey pals!
hope your prepration is going well....

we will discuss something about quant now.after a detailed discussions with my professors and other lecturers of quant i got some good knowledge which i would like to share with you.

first of all lets discuss why they actually want us to know quant?
- actually quant is the section which is segmented to test the aplicant's mental abilities to deal with figures.

you would be wondering like me about why they actually give so much importance to verbal calcultations (we have pcs, calculators and hell lot of equipments) but the answer is somewhat justified.

they want us to show how fast we are in playing with figures. the professor i talked about all this told me that you have to have a compatibility with figures because while reading company reports (some times from xx to xxx pages) and full of ratios and data figures, calculators and pcs become obsolete and mental abilities makes all the difference. they told me that the thin line between a good managerial decision and a bad one is actually generated from here only and i agreed him somewhat.

anyways the better reason to work on quant is - it is present in exam and you are not USA's president who can alter the exam style. so better learn it and rule the exam.

the main thing as mentioned above is figures and compatibility with them and to have a good gelling with figures you must be easy with calculations.

we are doing them from very first standard in schools and still have some kind of a fear left with in us about how to go ahead with them. so here is a solution to the problem-

VADIC MATHS

yes this is the sollution for all the problems or atleast most of them. after learning this you will wonder how easy it is to multiply and divide numbers which you wouldnt have even dared to add or subtract.percentages and proportioning will be not a difficult task at all.
it wont be easy but nothing to worry about. lets start this all together and lets see where we can reach.

we will start with vadic maths tricks and methods from the next post.
let me know if you are interested in these techniques.

Quant. resources

Hi friends.
Going through this blog you must have noticed that very little or almost no notice have been taken of the quant section of the GMAT,which is as important as all the other sections.
The reason behind this is that i truly believe that to gain excellence in this section you need to have and follow some basic stratergies.

1. Hardwork - Practice Practice and more Practice. Thats all i have to say about this section in GMAT . The best, and I think the only way of going about this section is sitting down with a bunch of good quant questions and working upon them and applying your brains in the process.

2. No shortcut or tips and tricks are their for this section .Its truly based on the amount of practice and hardwork you have putted into,the hours that you have spent over solving the questions, the time you have spent in learning all the formuales , the effort you have done to get the basics clear.

I can help you in the quant sections by providing some useful material for you to study with . I will provide my readers with 3 very useful resources for the quant section . You can download them from below.



By going through the above resources i have listed, you can have a very good idea about the quant section . Practice well as this section truly tests the amount of hardwork and learning the student has gone through.

Important books for GMAT

Hi friends , how is it going .
My preparation had been a little inconsistent in past 2 weeks as i was very busy attending Job related chores and stuff . My apologies for not posting in the last week .I hope your GMAT preparation is going smoothly .
I fully agree with all those who think that preparing for exams like GMAT , GRE, CAT is much more better and economical online than joining a coaching institute.Those coaching institutes like IMS, Career launcher and allare just a big show off.The best place to study is the net . You can get all the resources ( I mean everything that you can ever want ) for free which the so called 'coaching institutes' will give you in return for a small fortune.
oke i think all of you got the point that online preparation is all goody goody but you will need to have some good physical books also to help start and get along with your preparation.Online reading and understanding is one thing but nothing can beat the old fashioned way of sitting down with a good book in hand and geting through and applying your brain in the process.

Its time now we get to buisness and get ourselves some good and trusted study material for our preparation.I have done some research on this and i have made up a short list of books that are very well acknowledged and trusted and you can start your preparation with them.

Kaplan GMAT, 2007 Edition: - Covers the whole of GMAT syllabus. Good comprehensive book

Cracking the GMAT - 2007 Edition by Princeton review

Kaplan GRE & GMAT Math Workbook – For starting preparation

Kaplan 800For advanced preparation

Sentence Correction GMAT Very good and comprehensive. A must have for your preparation.

These books are fully trusted and have been acknowledged worldwide by GMAT gurus. Excellent stratergies and the approaches to tackle GMAT are all given very nicely and comprehensively in these books. They are a must for every GMAT aspirant. You can buy them online on www.amazon.com or purchase them from any bookstore near your residence.

Reading Comprehension

hi friends

today we will continue with our verbal portion practice.
We will practice reading comprehension and look for the best methods to go about solving the reading comprehension , we will also be looking at some of the tips and tricks for solving the reading comprehension.

What is a reading coprehension

GMAT reading comprehension questions are meant to test your understanding of the implications, meanings, and structures presented in the passages. You can expect to see 2 to 4 passages of 200 to 400 words each, in the verbal section of the GMAT exam. Each passage will be followed by 4 questions. Because the GMAT is now a computer-adaptive test, you will only see 1 question at a time. The passage, however, will remain on your computer screen until you have answered all of the questions related to it.

There is a certain patterm that has been seen since the reafing comprehensions started coming in the MAT exams.This pattern shows us that RC's can be classified into 3 broad groups.You will get a passage in the exma from within these 3 groups.

1.Science - If the passage is from science group its most likely to talk about subjects like biology , chemistry , physics . These type of passages are very factual. You should to an initial skimming ( fats reading) of the passage and take note of any factual information given. These types of passages can be boring but they are simple and factual and therefore are relatively easyto do.

2.Social science - Typically, these passages deal with topics such as history, politics, and geography. These are enjoyable to read but the questions they pose can be a little dauting.Read carefully these passages and answer according to questions.You must read these passages slowly in order to answer the many inference questions they are sure to present.

3.Buisness - Business passages involve very difficult structures, and present questions that require you to infer information and even to determine the authors' moods and opinions. They need to be read slowly and carefully.

Tips and tricks

  • Use your scrap paper - Use your scrap paper to make very brief notes on the main ideas of each paragraph. This will be very useful as in computer based test these days you can do it on screen.
  • Read the first question before the you read the passage - As the exams these days are on computer you will only see 1 question of the passage , but be sure to read that before starting the passage .
  • Identify the type of passage you are reading - Identify the passage that has come in the exam and see which of the 3 categories i explained above it falls in , and go about it in that stratergy .
  • Practice is the key - Nothing can beat the hardcore practice . The best way is to read as much u can before when preparing for the MAT and learn the various reading techniques.
