To score 700+ on the GMAT, test takers must develop a strategy to answer the Quant questions in 2 minutes and Verbal questions in 1 minute & 20 seconds. Data sufficiency questions can be solved well within the 2-minute mark, most likely in 1 minute and 30 seconds if the conditions and question are rephrased. Not all questions will be required to be rephrased but there are certain conditions where this technique is extremely useful, especially when concepts in Ratio & Proportion, Equations, Inequalities & Divisibility are tested.

Equations

This is the most common question type where rephrasing the conditions might be useful, especially in quadratic equations, and questions that require finding roots.

Let us look into a quadratic equation question type

For the following equations with positive roots, the value of k is greater than one

1) 3x^2 +5x + 2k = 0

2) (x+1)(3x+2) + 2k - 2 = 0

1) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.

2) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

3) BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.

4) EACH statement ALONE is sufficient to answer the question asked.

5) Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

If test takers straight away solve each equation separately without finding any relation between the two, the target of correctly answering the question in 1 minute and 30 seconds will not be reached. When it is a quadratic equation, just look at how the equation is formulated and notice if there are any relationship between the two equations.

As you might have noticed, on solving equation 2

(x+1)(3x+2) + 2k - 2 = 0

We get

3x^2 +5x + 2k

Both Statements are equal

Can we conclusively say that the value of k is greater than 1? The question tells us that it has positive roots.

To get positive roots for 3x^2 +5x + 2k

X has to be 3 and 2 or k = 1

Therefore, K is equal to 1.

Correct Answer: D, Both statements independently will give us the answer.

Inequality

Another scenario where the two statements might be the same on rephrasing is inequality questions. The options can be tricky when absolute value concepts are tested

What is the value of x?

1) |x-3| < -2

2) |x^2 + 5x + 6| > 0

Rephrasing statement 1, we get

|x-3| < -2

Positive solution

(x-3) < -2

X < 1

Negative Solution

-(x-3) < -2

-x +3 < -2

-x <-5

X > 5

X < 1 and x > 5 -> Rephrasing Statement 1

Rephrasing statement 2, we get

|(x+3) (x+2)| > 0 or

= (x+3)(x+2)> 0 and - (x+3)(x+2) > 0

= (x+3)(x+2)> 0 and (x+3)(x+2) < 0 (Sign reversed on multiplying negative on both sides

of the equation -> Rephrasing Statement 2

Answer Choices**Rephrasing the conditions in the equation, we get:**

What is the value of x?

1) X < 1 and x > 5

2) (x+3)(x+2)> 0 and (x+3)(x+2) < 0

This might look like a lot of calculation but the rules of absolute value inequalities are simple

Divisibility – Rephrasing Question

Not all GMAT Data Sufficiency rephrasing is operated on the two conditions. Carefully rephrasing questions can lead to easier problem solving.

Is 3+ 2n divisible by 3?

1) n is odd

2) n^2 is a multiple of 3

If you rephrase the question, it would look like

Is 2n a multiple of 3?

Ratio & Proportion - Rephrasing Question & Conditions

Another common GMAT DS question where rephrasing is effective is the Ratio and Proportion question.

Q) At the start of the annual shareholders conference, the number of men and women were in the ratio 4:5. 100 participants joined the conference 10 minute late, what is the new ratio of men and women?

1) If two more men were to join the conference after 20 minute, the ratio of men and women will be 7:8

2) 50 participants left the conference after 30 minutes, changing the ratio of men and women to 3:4.**Rephrasing questions and conditions to equations are most effective for solving lengthy GMAT data sufficiency questions.**

Q) N participants joined a conference with x men and y women in a conference such that x:y = 4:5. 100 participants joined the conference 10 minute late, what is x:y?

1) (X+2)/ y = 7/8

2) N – 50, x/y = 3/4

Once you have rephrased the question to equations, it becomes easier to solve this GMAT DS Question.

With Statement 1, we get two equations in x and y, which is sufficient to find x:y

With Statement 2, we get equations with x, y and N, which is not sufficient to find the ratio, x: y

**Reviews**

"I have not reviewed many books for MBA Admission consulting companies but doing it now to give all applicants a brief idea on what the book covers. The book includes 31 top MBA programs - almost all the top schools you have heard or considering for your MBA application. Each chapter is categorized by US States where there is at least one top MBA program. So you have California and Massachusetts with the most number of MBA programs and several states with one top program (Washington, Minnesota, Washington D.C., Connecticut, Virginia, and Maryland) and other states with two to three MBA programs. The book focuses on four aspects of an MBA program - curriculum, cost, class profile and post-MBA salary. For me, the breakdown of the cost and post-MBA industry was useful to make my decision on selecting the top 5 programs for 2017-18. It is a fascinating read in an industry where consultants overprice for their expertise. I recently bought a 30-page guide for $49. Compared to the obvious observation in that book, the 300+ page, MBA in US - the Ultimate guide is a goldmine of information and analysis." -

**Verified Purchase (21st June 2017)**

"I bought the ultimate guide after a friend recommended it for me. The guide covers a lot of ground on the history of each prominent US states and goes into the reasons why a certain industry emerged from each state. In addition to the analysis of the economy, trends and expected changes in the next 5 years, the book features top MBA programs in each state with an extensive study of its curriculum. Ultimate guide is an essential reference book for MBA Applicants if they want to shortlist MBA programs based on value and cost, and not just ranking. " -

**Verified Purchase (14th June 2017)**

"Should be a required reading before applying for an MBA. School events and MBA Tours are PR events disguised as a Q&A. On the contrary, the book is an unbiased analysis of each Top MBA program in the US supported by a large dataset and historical context on each industry. The guide builds a case for indstries that are likely to emerge as favourite for MBA graduates. Thorough and a valuable book."

**- Verified Purchase (15th June 2017)**

"What I liked: The breadth of the information. Some of my favorite nonfiction books have taken the same approach as the ultimate guide have - cover background information in-depth. In the book, the author uses parallel threads to demonstrate the history of the state and the rise of industries. Will make you think how schools thrive based on the policy set by the state. California's obsession with Technology has revolutionized how we do Business and changed post-MBA trends. Many MBA applicants will be consulting or doing marketing for a Technology company. That is one key finding from the book. The latest development in AI, FinTech, and Automation is an additional context that I found valuable in the book.

Very informative. I would recommend that you read the book at least once in chronological order before using Table of Contents." -
