### MBA aspirants preferring Indian Bschools over foreign Bschools

As per figures available with GMAC, 42% of the full time MBA programs in the US reported a decline in the number of foreign applicants, of these as many as 70% reported the largest decrease in number of applications from India, says a recent report.

Many MBA graduates claim that a one-year program from an Indian Bschool will get a better job profile in India (if he wants to settle and work in India) than a foreign MBA. Cost is also another major factor which makes MBA aspirants apply to Indian Bschools (which use GMAT scores for admission). MBA aspirants perceive that Indian schools offer quality education at a comparatively lower cost.

There are 24 Indian bschools (including select programs from the IIM’s) which accept GMAT scores.

A partial list:

ISB Hyderabad, GLIM Chennai, NMIMS Mumbai, IIMA PGPX, MDI PGPX, Exec MBA programs from top B-schools…..

### Hypothesis testins as a tool for GMAT math problem solving

Certain problems require you to formulate a hypothesis and verify. The relationships between relevant variables which are yet unknown but promise to offer solution in full or in part forms the basis of this method. Such formulations are tested for validity and accepted or rejected. More than one hypothesis can be formulated in a problem context. These hypothesis have to be examined and reformulated.

Errors which occur during hypothesis testing

(1) Overlooking certain data

(2) Overemphasizing data which give positive conclusions while failing to give sufficient importance on data which falsifies information.

The following sum is a tough mathematical problem where skill of hypothesizing information and testing it comes forth.

This sum takes a long time if you solve by writing equations.

It can be solved faster by hypothesizing a data and testing the hypothesis wrt to other conditions.

First let us interpret the problem carefully and diagram it.

Information which is direct

• 15 years back Mrs. John had only three children Rachael, Mary and Annie. Mrs. John’s age was double the sum of the ages of her children.

• Sometime between 15 and ten years back, Thomas was born. At that time Mrs. John’s age was equal to the sum of the 3 children

• Between 10 years back and present time, George was born. At that time Rachael was as old as Mary and Thomas together.

• At present the combined age of all the children is double Mrs. John’s age. Mrs. John’s age is equal to the sum of Rachael and Annie. Rachael’s age is equal to the sum of George and Thomas

• All the ages are whole positive number, there are no fractions.

• Thomas’s age must be less than 15 and near 15. As 15 years back Mrs. John had only 3 children

• The last statement states that Rachael’s age + Annie’s age = Mary’s age + Thomas’s age + George’s age.

Rachael’s age = George’s age + Thomas’s age and Mrs. John = Rachael’s age + Annie’s age

Where T is Thomas age, A is Annies age and G is Georges age

We can conclude that Annie and Mary were twins

We will assume data from the questions

Let us hypothesize that Thomas’s age is 12. (9 is far away from 15).

{If we don’t get the answer using T =12 we can conclude that T = 9. Other options are wrong.}

Lets verify our hypothesis.

Rachael must be the eldest daughter . Let us assume that Rachael age must be 21 other options are close to 15 and as she is the eldest we will assume the biggest number

So George’s age must be 9 ( question 4 seems to be satisfied)

Mrs. John - Time line- Rachael-Annie-Mary-Thomas-George

Using the info: Between 10 years back and present time, George was born. At that time Rachael was as old as Mary and Thomas together.

It can be concluded that Mary was 9 as 12 = Mary’s age + 3

Hence Annie’s age was also 39

Filling our table

All the children’s age 9 yrs back can be calculated.

Their present ages can also be calculated including Mrs. John age

Mrs. John - Time line- Rachael-Annie-Mary-Thomas-George

Mrs. John - Time line- Rachael-Annie-Mary-Thomas-George

Now the table can be completed and the all the answers can be calculated

What is Mrs. John’s age? - 39

What is the age of the eldest daughter? - 21

What is the age of the eldest son, Thomas ? -12

What is the age of the youngest child? - 9

Errors which occur during hypothesis testing

(1) Overlooking certain data

(2) Overemphasizing data which give positive conclusions while failing to give sufficient importance on data which falsifies information.

The following sum is a tough mathematical problem where skill of hypothesizing information and testing it comes forth.

*Fifteen years back Mrs. John had only three daughters Rachael, Annie, Mary and their combined age was half of hers. During the next 5 years, Thomas was born. At that time Mrs. John’s age equaled the total of all her children’s ages. After some years George was born and then Rachael was as old as Mary and Thomas together. And now, the combined age of all the children is double Mrs. John’s age, which is only equal to that of Rachael and Annie together. Rachael’s age is also equal to the combined age of the two sons’.*

*What is Mrs. John’s age?*

*1. 39 2. 34 3. 29 4.24*

This sum takes a long time if you solve by writing equations.

It can be solved faster by hypothesizing a data and testing the hypothesis wrt to other conditions.

First let us interpret the problem carefully and diagram it.

**PROBLEM ANALYSIS**Information which is direct

• 15 years back Mrs. John had only three children Rachael, Mary and Annie. Mrs. John’s age was double the sum of the ages of her children.

• Sometime between 15 and ten years back, Thomas was born. At that time Mrs. John’s age was equal to the sum of the 3 children

• Between 10 years back and present time, George was born. At that time Rachael was as old as Mary and Thomas together.

• At present the combined age of all the children is double Mrs. John’s age. Mrs. John’s age is equal to the sum of Rachael and Annie. Rachael’s age is equal to the sum of George and Thomas

**Implicit information**• All the ages are whole positive number, there are no fractions.

• Thomas’s age must be less than 15 and near 15. As 15 years back Mrs. John had only 3 children

• The last statement states that Rachael’s age + Annie’s age = Mary’s age + Thomas’s age + George’s age.

Rachael’s age = George’s age + Thomas’s age and Mrs. John = Rachael’s age + Annie’s age

**PROBLEM CONVERSION**Mrs. John - Time line- Rachael-Annie-Mary-Thomas- George

T+G+A - Present - T+G -A -A -T -G

Where T is Thomas age, A is Annies age and G is Georges age

We can conclude that Annie and Mary were twins

We will assume data from the questions

Let us hypothesize that Thomas’s age is 12. (9 is far away from 15).

{If we don’t get the answer using T =12 we can conclude that T = 9. Other options are wrong.}

Lets verify our hypothesis.

Rachael must be the eldest daughter . Let us assume that Rachael age must be 21 other options are close to 15 and as she is the eldest we will assume the biggest number

So George’s age must be 9 ( question 4 seems to be satisfied)

Mrs. John - Time line- Rachael-Annie-Mary-Thomas-George

15 yrs back-6 -

12 yrs back-9 - -0(Thomas born)

10 yrs back-11 - - 2

9 yrs back - 12 - -3 -0(Georges born)

5 yrs back - 16- 7 - 4

T+G+A Present -21 - A- A- 12 - 9

Using the info: Between 10 years back and present time, George was born. At that time Rachael was as old as Mary and Thomas together.

It can be concluded that Mary was 9 as 12 = Mary’s age + 3

Hence Annie’s age was also 39

Mrs. John - Time line- Rachael-Annie-Mary-Thomas-George

9 yrs back- 12 - 9 -9 - 3 - 0(Georges born)

Filling our table

All the children’s age 9 yrs back can be calculated.

Their present ages can also be calculated including Mrs. John age

Mrs. John - Time line- Rachael-Annie-Mary-Thomas-George

39 - Present - 21 -18 - 18 - 12 - 9

Mrs. John - Time line- Rachael-Annie-Mary-Thomas-George

24 - 15 yrs back - 6 - 3 - 3

-12 yrs back - 9 - 6 - 6 - 0(Thomas born)

- 10 yrs back - 11 - 2

- 9 yrs back - 12 - 9 - 9 - 3 -0(Georges born)

- 5 yrs back -16 - 7 - 4

39 -Present - 21 - 18 - 18 -12 - 9

Now the table can be completed and the all the answers can be calculated

What is Mrs. John’s age? - 39

What is the age of the eldest daughter? - 21

What is the age of the eldest son, Thomas ? -12

What is the age of the youngest child? - 9

### Financing your MBA

Recession or no recession, a MBA degree from USA or UK remains the number one priority for many undergraduate/ graduates in countries across the world. The only constraint for many students is the huge fee.

Public sector banks in India for instance offer loans up-to INR 20 lakhs, interest rates vary from 10-13%.Banks abroad provide similar funding. In fact there is a concession ranging from 50 – 100 basis points for female students.

Banks insist on students depositing 15% of the total loan if the overseas loan size exceeds Rs.4lakhs. No collateral is required for loans up-to Rs.4lakh. For loans beyond INR 4lakhs it is required to furnish suitable tangible collateral security like fixed deposits, NSS etc.

Repayment of loans begins immediately after student secures employment or six months, post completion of the course. Repayment tenure is 5 years to 7 years.

It is also possible to get loans from banks based in the US. Several B-schools have tie up with banks, it is advisable to apply to those colleges which offers loan cum admission.

To get scholarships in the UK visit www.ukba.homeoffice.gov.uk and check whether your educational provider is registered with UK border agency.

Cost of MBA program in the US : $25000-$70000 per annum*

Cost of MBA program in the UK : 10000- 40000Pounds per annum*

*inclusive of tuition fee and living expense.

### Science of high performance in the GMAT -1 : Is GMAT Official guide sufficient?

Official guide- published by the GMAC has a list of 800+ questions (11th edition). There are around 230 problem solving (math) questions.. However I feel that this list represents the easier problems in the GMAT.

To break into the 720+ it is imperative that you have to solve tougher higher difficulty problems. (This is true for the verbal section also)

A higher order problem is problem which has

• A situation which can otherwise be solved by identifying the concept/formula and applying the same directly

• A complexity present in the problem which acts as a stumbling block, thereby preventing you from getting an answer directly.

When approaching a higher problem first

Try this problem independently first, then read further.

Let me take you through the problem in the science of thinking* approach toward higher order problem solving.

Eliminate the complexity first

If the car didn’t stop at 11:30 then the time taken by both the bodies to meet is determined using the relationship

Time taken to meet = Initial distance between the bodies/ relative velocity

= 48/(45 -30) { Relative velocity when two bodies move in the same direction = difference of their speeds, hence 45-30 =15)

= 48/15= 3.2hrs

As you would have observed if the complexity is eliminated the problem can be solved directly. As per the problem. The car travels till 11:30 and then stops for 15mins. So you might calculate the distance travelled by each body from 10:00 till 11:30 and then calculate the distance travelled by the two wheeler for that extra 15mins and then proceed. This complicates the problem.

Instead you can restructure the problem in such a way that the complexity gets integrated into the problem and doesn’t get noticed.

Here you can shift the 15min time interval from 11:30 to 10:00 such that the car starts only at 10:15 instead of 10:00. Hence the initial distance increases from 48 to 48 + (distance travelled by two wheeler for 15mins) = 48 + 7.5 =55.5kms

Hence now there is no stoppage time at 11:30.

Time taken to meet = Initial distance between the bodies/ relative velocity

= 55.5/(45 -30) = 55.5/15= 3.7hrs = 3hrs 42minutes

Meeting time =10:15 + 3 : 42 = 13: 57

You would get higher order problems only if the adaptive algorithm decides that you deserve questions of this difficulty.

So for those of you who aim to crack the 720+ barrier. Practice on higher order problems.

**What is a higher order problem?**A higher order problem is problem which has

• A complexity present in the problem which acts as a stumbling block, thereby preventing you from getting an answer directly.

When approaching a higher problem first

- Identify the concept involved
- Identify the complexity in the problem
- Remove the complexity and if possible arrive at a result
- Modify the complexity in such a manner the complexity gets integrated into the problem and this results in a newer problem
- Solve the new problem by directly applying the concept.

A car moving at 45 kmph and is chasing a two wheeler that is moving at 30 kmph. The distance between the car and the two wheeler at 10:00 am is 48 kms. The car stops at 11:30 am for 15 mins to fill fuel and moves at 45 kmph. When will the car meet the two-wheeler?

1.12.42 pm 2.1:42 pm 3.1:57 pm 4. 1:47 pm 5. 1:30pm

Try this problem independently first, then read further.

Let me take you through the problem in the science of thinking* approach toward higher order problem solving.

**The concept –**Time, speed and distance, Relative velocity involving two bodies moving towards each other.**The complexity**– The stoppage time of the car. At 11:30 am the car stops for 15 mins.Eliminate the complexity first

If the car didn’t stop at 11:30 then the time taken by both the bodies to meet is determined using the relationship

= 48/(45 -30) { Relative velocity when two bodies move in the same direction = difference of their speeds, hence 45-30 =15)

= 48/15= 3.2hrs

**Modification of the complexity**As you would have observed if the complexity is eliminated the problem can be solved directly. As per the problem. The car travels till 11:30 and then stops for 15mins. So you might calculate the distance travelled by each body from 10:00 till 11:30 and then calculate the distance travelled by the two wheeler for that extra 15mins and then proceed.

Hence now there is no stoppage time at 11:30.

Time taken to meet = Initial distance between the bodies/ relative velocity

= 55.5/(45 -30) = 55.5/15= 3.7hrs = 3hrs 42minutes

Meeting time =10:15 + 3 : 42 = 13: 57

You would get higher order problems only if the adaptive algorithm decides that you deserve questions of this difficulty.

So for those of you who aim to crack the 720+ barrier. Practice on higher order problems.

### Pattern recognition as a skill to solve GMAT math problems

Many math problems are based on patterns. These problems may involve a set of numbers or a set of alphabets or maybe even a set of figures.

The skill is in

This sum involves a set of even numbers from 1 to n.(n is an odd number)

Lets derive the pattern

First let n =5

Then the even numbers involved are 2,4

Hence, Sum = 2+4 = 6

6 can be written as 2 *3( Same pattern as 79*80)

Now let n =7

The even numbers are 2,4,6

Sum = 2+4+6 = 12 i.e 3*4

So you get a pattern 2*3, 3*4…………………….79*80, when n = 5,7……n

Do you observe that 2+3 =5 and 4+3 =7, 4+5 =9

This leads to the answer.

Bookmark this on Delicious

The skill is in

- Identifying patterns
- Taking a sample and deriving meaning full relationships between the various elements in the pattern
- Expostulating the pattern to encompass the entire series
- Use this new knowledge to arrive at an answer

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

This sum involves a set of even numbers from 1 to n.(n is an odd number)

Lets derive the pattern

First let n =5

Then the even numbers involved are 2,4

Hence, Sum = 2+4 = 6

6 can be written as 2 *3( Same pattern as 79*80)

Now let n =7

The even numbers are 2,4,6

Sum = 2+4+6 = 12 i.e 3*4

So you get a pattern 2*3, 3*4…………………….79*80, when n = 5,7……n

Do you observe that 2+3 =5 and 4+3 =7, 4+5 =9

This leads to the answer.

**In a nutshell: when you encounter problems which ask you to compute the value for n terms****Take a small sample and analyze.(Relate the analysis to the answer)****Take another sample and analyze****Write the result together and derive a relationship among the numbers****This leads to the answer.**

### How to cross the magical 700 score barrier in the GMAT -1

So you are at your fag end of your preparation. You have just completed a GMAT CAT, you got a score of 640. You also notice that your score has been hovering around 600 to 650. Well you are not alone.

A recent survey states that the average GMAT score is 560, down 10 points when compared to last years average. How is that few people cross 700 whereas the rest of the test aspirants(approximately 2,00,000 out of 2,65,000 GMAT takers) languish in mere 600’s?

Here is my 2 cent

The GMAT score is an indicative of the current aptitude level of an individual. Your aptitude quotient doesn’t improve over night. It takes at-least 3 months of preparation to improve your score. So what is POA right now.

It is better to work on a question 10 times than working on 10 different questions. Aptitude exams don’t test your knowledge of formula. It tests you on your application of concepts.

Study each problem 10 times, observe the parts a problem

•

•

•

These parts of the problem indicate the steps and the time taken to solve the problem. This factor results in effective time management.

To improve your math preparation, reason with mathematical problems.

For example

To solve this sum reason with the problem:

5^1 and 2^1 gives 10

5^2 and 2^2 gives 100 or 10^2

5^3 and 2^3 gives 100 or 10^3

The pattern is one 5 and one 2 gives 10, two 5’s and two 10’s gives 100…. The number of 5’s and the number of 2’s gives the number of 0’s.

Conclusion one 5 and one 2 gives one 10 or a number with one 0.

Hence 5^25 x 2^32 = 5^25 x 2^25 x 2^7

Which is 128 …….(25 times)

Most mathematical problems in the GMAT are related to the method of deriving certain standard formula than the formula itself. For example

While deriving the area of the equilateral triangle = sqrt(3) side^2/4

Study the CR questions in groups. For example study all “the weaken the argument” questions together. You will observe standard steps every time.

Simple aint’ it.

5. If you are not strong with sentence correction and reading comprehension till now and if you have only two weeks to go, then there is nothing that can be done. It requires at-least 3 weeks of structured learning.

Use any course ware you have or use the course ware which I have recommended. Its on your right pane. Or if you don’t have the right material mail me ill help….:-)

5^3 and 2^3 gives 100 or 10^3

The pattern is one 5 and one 2 gives 10, two 5’s and two 10’s gives 100…. The number of 5’s and the number of 2’s gives the number of 0’s.

Conclusion one 5 and one 2 gives one 10 or a number with one 0.

Hence 5^25 x 2^32 = 5^25 x 2^25 x 2^7

Which is 128 …….(25 times)

**3. Do not revise just the formula, learn how to derive it.**Most mathematical problems in the GMAT are related to the method of deriving certain standard formula than the formula itself. For example

While deriving the area of the equilateral triangle = sqrt(3) side^2/4

**You will notice that the altitude bisects the triangle into two halves of equal area****The altitude splits the base into two halves of equal length.****4. Compare critical reasoning questions and derive generalization**.Study the CR questions in groups. For example study all “the weaken the argument” questions together. You will observe standard steps every time.

*For example you will observe you have**• to first find the conclusion**• then identify the logic( whether its an analogy, a statistical data, a cause effect relationship or an example)**• then choose the option that negates the logic*Simple aint’ it.

5. If you are not strong with sentence correction and reading comprehension till now and if you have only two weeks to go, then there is nothing that can be done. It requires at-least 3 weeks of structured learning.

Use any course ware you have or use the course ware which I have recommended. Its on your right pane. Or if you don’t have the right material mail me ill help….:-)

### Number of GMAT test takers

GMAT was taken 265613 times in the testing year 2009*. “Total GMAT volume is up, but by breaking down the figures by country, by world region, by gender, by intended degree, and by age, we see a very complex picture emerge,” says a senior official from GMAC.

**Some highlights from the GMAC report**- The number of GMAT test takers have been rising for the past five years
- The number of tests takers under 24 continues to rise rapidly
- The percentage growth of number of tests takers has increased the greatest in central/south asia followed by Australia/Pasific islands, Europe and finally Canada.

- The overall mean GMAT score is down one point, to 539

### GMAT sentence correction

The GMAT verbal section is the toughest section in the test. For this the section that appears after two long sections of writing and math. It induces undue strain on the test taker. Besides this section is concept intensive unlike any other aptitude test.

Besides, each question type is long sentence or paragraph based requiring extensive reading of verbal information.

The sentence correction questions (14/15) of them tests correctness and effectiveness of expression. You have to choose the option that conforms to standard written English; you have to pay attention to grammar, syntactical constructions, diction, clarity and semantic conformity.

Listed below are those concepts that you should learn for excellence in the sentence correction question.

1. Subject Verb disagreement

2. Parallel structure

3. Idiomatic constructions

4. Misplaced Modifier

5. Tense consistency

6. Countable, non-countable nouns

7. Pronoun-noun agreement

These are just 7 of the 25 errors tested in GMAT.

Read more about the errors at

http://www.semanticslearning.com/gmat-usage.asp

Here “Annoyed by the corporation’s apathetic attitude”, should modify the residents, hence the correct construction is

“Annoyed by the corporation’s apathetic attitude, the residents decided to install an incinerator for garbage disposal.”

Here which and it are unclear are ambiguous. Which can wrongly refer to stomach, analgesics or irritation.

The unambiguous construction is

“The irritation caused in the stomach by the intake of analgesics can be avoided if the analgesic is taken in capsule form.”

### Math Problem solved using ScoT

I got a query from a in this problem. I solved using Science of Thinking(ScoT) approach.Observe the problem solving process.

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

These type of sums can be solved using my thinking skills – “pattern recognition” and “hypothesis testing”

Take sum of even numbers when n =5( N has to be an odd number)

Sum = 2+4 = 6 i.e 2 *3( Same pattern as 79*80 i.e n*(n-1))

Now take sum of even numbers when n = 7

Sum = 2+4+6 = 12 i.e 3*4

So you get a pattern 2*3, 3*4…………………….79*80

When n = 5,7……n

Do you observe that 2+3 =5 and 4+3 =7.

So our hypothesis is that n should be sum of the product of the numbers(in the form n*(n-1) which yields the sum of the even numbers.

Now lets check our hypothesis

When n =9

Sum = 2+4+6+8 = 20 = 4*5

4+5 is equal to n

Hence n can be concluded as 79+80=159

### Analyzing GMAT math problems using the Science of Thinking(ScoT) approach

The first step in the problem solving process is problem analysis. Problem analysis comprises

Let me explain the process of classification of problem based on their definition now.

Problems can be classified as a poorly defined or a well defined problem.

A well defined problem everything relevant and required is clearly specified, without any ambiguity or uncertainty, such that a solution, even if it involves complex calculations can be arrived at with accuracy. You can predict the path to take or steps required to solve the problem.

A poorly defined problem much of the data & relationships are hidden or not clear.

Lets take a poorly defined problem.

The data present in the above question is cryptic. The interpretation of this problem lies in your ability to attach meaning to the verb tense.

To analyze the above problem you have to represent the problem diagrammatically to understand the relationship between the variables.

Try creating a table with the past ages, present ages and future ages as the columns. Given below is a simplified version of the table.

### 5 crucial points to keep in mind while attempting a Data sufficiency problem

of the equation don’t match. Hence x only has to be 0.

4. Do not make any assumptions of the figure drawn. If a four sided figure is drawn with straight line, do not assume it’s a square or if a point is marked in the middle of a circular region, don’t assume it’s the centre of the circle.

5. Although Data sufficiency tests your decision making skills (choosing which statement is sufficient) it is advisable to spend some time arriving at an answer and checking whether the answer derived is always true or always false.

### 5 crucial points to be kept in mind while solving a probability based problem in GMAT

1. Calculate the numerator {Number of favourable terms} and the denominator {Total number of terms} separately using the concepts of arrangement, permutation and combination.

2. Be part of the problem : Imagine you are arranging / selecting the items. The action of taking the object and placing it in the relevant position is the key.

If you have to arrange 10 rings in 4 fingers, you have to imagine yourself picking a ring and placing it on a finger instead of computing the number of rings each finger has.

3. When two or more items are picked it is easier to compute the probability of picking one element at a time than computing the probability of picking many items at a time.

4. When A and B are selected relate the respective probabilities with multiplication. When either A or B is selected relate the respective probabilities with addition.

5. When there are multiple outcomes possible the probability of at-least one of them happening is computed by calculating the reverse probability

= 1 – probability of event not happening.

### 5 crucial points to keep in mind while solving a permutation combination problem

1.ARRANGMENT N terms can be arranged in N! ways, if each position can be occupied by one term. N terms can be arranged in NM ways if each position can be occupied by 1 term or 2 terms or …… N terms. M stands for the number of positions to be filled.

2.COMBINATION M terms can be selected from P terms in [ (P)combination(m) ] ways.

3.In certain situations it is required to first choose the terms and then arrange the terms. i.e. PERMUTATION. Permutation = combination x arrangement.

4.When N objects are distributed among P positions such that each position can get any number of objects (zero, one, two ……N) then the number of ways of arranging the items is [ (N+P-1) combination (P-1) ]

5.When N objects are distributed among P positions such that each position can get atleast one objet (one, two ……N) then the number of ways of arranging the items is [ (N-1) combination (P+1) ]

2.COMBINATION M terms can be selected from P terms in [ (P)combination(m) ] ways.

3.In certain situations it is required to first choose the terms and then arrange the terms. i.e. PERMUTATION. Permutation = combination x arrangement.

### 5 most overlooked points while solving GMAT triangle based problems (under Geometry)

- Similar triangles are triangles whose sides are proportional. If ABC and PQR are two similar triangles then AB/PQ = BC/QR =AC/PR. The angles opposite to the sides(which are in a ratio) are also proportional

- Area of a triangle(sides are a,b,c) is based on the hero’s formula

s= (a+b+c)/2 , R = circum radius and r= inradius

3. The sum of two sides of a triangle is greater than or equal to the third side and the difference of any

two sides is lesser than or equal to the third side. This property is used extensively in GMAT higher

difficult problems4. For the equilateral and the isosceles triangle the altitude bisects the base and hence the triangle into

two equal parts

5. The largest triangle (with the maximum area) which can be inscribed in a circle is the equilateral

triangle.

### Stanford’s new admission policy

Most sources say that while applying for a Bschool,it does not matter when you send your application(1 year earlier or 1 day before the deadline), because they will read your application until the application deadline passes.

But Stanford it seems have articulated a policy that they will review the admission application and inviting applications for interviews before its first round deadline passes. This has been designed in order to balance the work load of the admission committee.

Although it is advisable to rush your application procedure, it is better to apply when you think you are ready.

### 5 most overlooked points while solving GMAT number based problems (Arithmetic based problems)

The 5 series!!!!

5 most overlooked points while solving GMAT number based problems (Arithmetic based problems)

1.Study the factors of a number. Factors of a numbers are numbers which can divide that number. The factors for 28 are1, 2, 4, 7, 14, 28. Factors are always smaller than a number. The number of factors for a square is always odd.

2.Study the multiples of a number. Multiples of a number are numbers which are obtained by multiplying a given number by a constant. When you want to combine two numbers use LCM. For example : What is the smallest 4 digit number which can be divided by 2,5,6,8 and 9. To solve this sum first: you would have to combine these numbers to arrive at a common number i.e.the LCM of 2,5,6,8 and 9 and then proceed to obtain the smallest 4 digit number.

3.Any number raised to the power of 4 will lead to a number (say k)whose last digit remains the same irrespective of the number of time the number is multiplied with itself.(k x k x k…..n times where n can be any integer)

4.Let a × b = c. The remainder obtained when you divide c by d is equal to the product of the remainders obtained when you divide a by d and b by d. Instead of finding the remainder of 625 when divided by 7 it would make sense find the remainder of 25 when divided by 7 and multiplying the remainder twice to get the overall remainder( 625 =25 x 25)

5.While solving number based data sufficiency problems substitution of all possible numbers (positive integers, negative integers, positive fractions, negative fractions, zero) is necessary before arriving at an answer.

For example: Is (a/b) > (c/d)

1. a > c

2. b >d

Each statement individually will not yield an answer. When the statements are taken together substitute positive numbers, negative numbers to check the consistency of the answer. Also substitute numbers which are near each other as per the number line (a=2,c=1) and numbers which are far away (a =1000, c=1)

3.Any number raised to the power of 4 will lead to a number (say k)whose last digit remains the same irrespective of the number of time the number is multiplied with itself.(k x k x k…..n times where n can be any integer)

4.Let a × b = c. The remainder obtained when you divide c by d is equal to the product of the remainders obtained when you divide a by d and b by d. Instead of finding the remainder of 625 when divided by 7 it would make sense find the remainder of 25 when divided by 7 and multiplying the remainder twice to get the overall remainder( 625 =25 x 25)

5.While solving number based data sufficiency problems substitution of all possible numbers (positive integers, negative integers, positive fractions, negative fractions, zero) is necessary before arriving at an answer.

For example: Is (a/b) > (c/d)

1. a > c

2. b >d

Each statement individually will not yield an answer. When the statements are taken together substitute positive numbers, negative numbers to check the consistency of the answer. Also substitute numbers which are near each other as per the number line (a=2,c=1) and numbers which are far away (a =1000, c=1)

### How to take charge of you GMAT math section?

To get a high score in the GMAT, you must be familiar with the relevant concept/formula as well as the hidden relationships accompanying the concept/formula. Many of us attempt to crack the math section of the GMAT by solving problems from sources such as the official guide.

This strategy works for people who have a strong mathematical background. For the rest of us, we have to first understand the concepts, then we have to derive relationships from the existing concepts.

Concept learning is an art. We look at a math text book and we get overwhelmed by the size. 20 odd chapters!! How am I going to master all of them? Each topic looks menacing.

But if you observe closely not all the concepts are abstract, a time speed distance problems is related to a problem based on similar triangles(geometry), a problem on roots of an equations is based on factor theorem in number system. The concepts required to crack GMAT math are inter- related.

The quantitative section is primarily focussed on number system, ratios proportion and percentages. Majority of the other concepts are based on these concepts. Focus on these areas first, then apply these concepts to study other concepts like Time and work, Geometry, Profit, loss and discount,.

So from 20 odd chapters the area of focus boils down to 3 or 4 chapters.

Also: Make derivations

While working out practice problems at the conceptual level, derive notes on where you can apply the concepts. Some of these derivations are highlighted below.

Presented below are some of the hidden relationship accompanying the concept/formula. These relationships are termed ScOT bytes which are the present through out our course material.

*1. Let A and B be two numbers, then Product of A and B = HCF (A, B) × LCM (A, B)*2. (Even number)

^{4x}will always end in the digit: ‘6’,(Odd number)^{4x}will always end in the digit: ‘1’

*3. Let a × b = c. The remainder obtained when you divide c by d is equal to the product of the remainders obtained when you divide a by d and b by d.*

**5. If a is increased/decreased by b%, then the new value calculated after the increase is new value = a**

**±**

**b% of**a

**±**

**(b/100) x a**

7. If a same positive number is added to both the terms of ratio (of lesser inequality), then the ratio is increased.

8. If a same positive number is added to both the terms of ratio (of greater inequality), then the ratio is diminished.

9. The number of factors for a square number is always odd. For 4 there are 3 odd factors(1,2,4), for 9 there are 3 odd factors(1,3,9)...

10. Discount percentage is always calculated on list price/marked price and not on selling price.

11.If a:b = 3:4 then a and b are not equal to 3 and 4 respectively. a = 3x and b = 4xwhere x is any constant.

12. The Simple and compound interest is the same after 1 year. The amount as well as the compound interest increases by r% every year.

Where r1,r2,r3 are interests and n1,n2

and n3 are the years.

14. To convert km/hr into m/sec multiply the number by 5/18

15.Average speed can be calculated by 2ab/(a+b) where a and b are the two speeds. This formula is only applicable when the distance travelled is constant.

### Planning to study abroad

The general trend is that students aspiring to study abroad tend to apply for programs which they think will positively impact on their future earning potential.

If you are interested in studying for a course apply early because competition for entry to popular programs at good institutions is severe; an early application helps to secure both admit and financial support.’

The US, UK, France, Italy, Spain, Australia, Singapore and Canada, are ever on the list of those foreign bound. Attending education tours organsied by established agencies will help you gain information on suitable courses, application procedures, admissions criteria, visa requirements and scholarship opportunities.

The world MBA tour is offering an unprecedented US $ 1.1 million in exclusive scholarships for MBA. They are offered to candidates only if they visit the fair in their city of choice. So go for it.

Some factors

The average work experience that MBA schools generally look for in prospective students is

Three to four years, although each school has its own standards. Business schools are not faculty- focused; peer to peer interactive learning, case work, projects, presentations all demand strength of experience of the MBA students. People with some real experience can contribute to quality group participative learning. Experience can be in diverse fields and industries, not necessarily managerial.

For international students this is a concern. But cost, if viewed as ‘return on investment’ will scare you less. There are various ways to fund your business education- loans and scholarships. Schools will take extra care to ensure that the right applicants are absorbed into their courses.

The best study abroad experience can differ form country to country and institution to institution. And your interests, skills, specializations. The best for one student need not be the best for another. Let your personal aims and ambitions guide you in this. Research schools on an individual basis.

Both are sought after. Interest rate, pay back time, speed of sanction- are to be considered. The tuition fee is obviously one of the biggest costs. Market rate tuition fees, the current practice, favor students. Other expenses to be taken into account are travel, accommodation, living and compensating for time away from employment. These are not uniform and vary for students form different nationalities.

MBAs will not go out of fashion even during recession times. Most banks know that MBAs are going to be among the highest earners within a short space of time and they can work in most industries. One should not wait until an admissions decision is received to identify outside sources of funding. Keep researching for fellowships and scholarships.

Savings from your employment so far, family contributions, institutional scholarships and bursaries from your department of study, assistantships and part-time employment: (teaching / research assistantships are available in many institutions for postgraduate students, who can work up to 20 hours during term time)

*Australia and Canada, allow international students to work up to 20 hours per week during their studies.

### Know your biz gurus

Peter Drucker: 1909- 2005

Education: Doctorate in International Law and public law from the University of Frankfurt in 1931.

Peter Drucker has been called the world’s most influential business guru, whose thinking transformed corporate management in the latter half of the 20th century. Drucker started his career as a business strategist when he was invited to do what became a seminal two-year social-scientific analysis of General Electric. In 1950 he became professor of management in the graduate business school at New York University. Drucker taught management advice with interdisciplinary lessons from history, sociology, psychology and religion. He developed one of the country’s first executive MBA programs for working professionals at Claremont Graduate University, now known as Peter F Drucker and Masatoshi lto Graduate School of Management. Few know that the management visionary actually foretold the current financial crisis and the potential involvement of the US government with the financial companies.

Books authored: His ideas on management and leadership have been published in more than thirty books. Notable among them are:

* The Practice of Management

* The Concept of the Corporation

* Managing in a Time of Great Change

* Management Challenges for the 21st Century

Key Concepts: He advocated that business should be managed by balancing a variety of needs and goals, rather than subordinating an institution to a single value. This concept of management by objectives forms the keynote of - The Practice of Management.

In 1959, Drucker coined the term ‘knowledge worker’ and pioneered the idea of privatization. Later in his life he considered knowledge work productivity to be the next frontier of management. He believed in the empowerment of workers and the futility of big government, which he called ‘obese, muscle-bound and senile’.

CEOs who used his tactics: During his long consulting career, Drucker worked with many major corporations, including General Electric, Coca- Cola, Citicorp, IBM, and Intel. Drucker also served as a consultant for various government agencies including Salvation Army and the American Red Cross.
