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 2minute 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...

Categories : Absolute Value, Inequalities Good news, test takers! You can pass the GMAT! Most of the questions are not that difficult. The difficulty in the test is in taking a midlevel question, (5x2 = 10) and rephrasing it in a more difficult way. (5 men walk into a bar. The bartender gives each man a beer for each of their hands. How many beers does the bartender distribute all together?) There is one exception to the rule, though: Absolute value inequalities. 
Categories : Inequalities Quadratic Inequalities is an important and often misunderstood topic in GMAT. But before we start, let us recall what a quadratic equation is and how is it represented.
