III. DATA INSIGHTS

We know that ratios are the building blocks for a lot of other concepts such as time/speed, work/rate and mixtures. As such, we spend a lot of time getting comfortable with understanding and manipulating ratios, so the questions that test […]

Here is an often-repeated complaint we hear from test takers – Data Sufficiency questions that deal with number properties are very difficult to handle (even for people who find problem-solving number properties questions manageable)! They feel that such questions are […]

We know that ‘Easy C’ is a common trap of DS questions – have you wondered whether there could be trap called ‘Easy A/B’ such that the answer would actually be (C)? Such questions also exist! The point is that […]

Another method of saving time on simple questions – use data given in one statement to examine the other! Now you might think we have lost it! After all, you know very well that in Data Sufficiency questions of GMAT, […]

Today we will discuss a problem we sometimes face while attempting to solve Data Sufficiency questions for which the answer is option (E) (when both statements together are not sufficient to answer the question). Ideally, we would like to find […]

We discussed how to solve equations with the variable in the denominator. We also said that the technique generally works for Problem Solving questions, but you need to be careful while working on Data Sufficiency questions. Today, let’s look at […]
