In our everyday lives, we all understand that attention to linguistic detail is important. Similarly, if you were on the phone making plans with a friend, you’d never hang up before knowing what you’d made plans to do. Details aren’t just important – almost every conversation we have would be totally incoherent if we didn’t … Read more

We know the formula we need to use to find the sum of n consecutive positive integers starting from 1. The formula is given as n(n+1)/2. So the sum of first four positive integers is 4 * (4 + 1)/2 = 10. This might seem a bit cumbersome, since it is easy to see that … Read more

When a question offers multiple bits of information, starting with the last piece can often be a way of dramatically simplifying the problem. Take the following problem: Mary’s income is 60 percent more than Tim’s income, and Tim’s income is 40% less than Juan’s income. What percent of Juan’s income is Mary’s income? A) 124% B) 120% … Read more

People with a statistics background will be very comfortable with it, but if you have not studied statistics, a little bit of knowledge will be helpful. You are not required to know this for theCAT, however there could be questions framed on the sampling premise, and you will be far more comfortable solving them with some understanding in place. A … Read more

They say Mathematics is a perfect Science. There is a debate over this among scientists but we can definitely say that Mathematical methods are not perfect so we cannot use them blindly. We could very well use the standard method for some given numbers and get stranded with “no solution.” The issue is what do … Read more

The material covered on the exam is not inherently complicated, but the combination of subtle wordplay and constant stress about time management creates an environment where test takers often rush through prompts and misinterpret questions. Unfortunately, time management and stress management are two of the major skills being tested on the CAT, so the time … Read more

Let’s take up a conceptual discussion on expressions and equations and the differences between them. The concept is quite simple but a discussion on these is warranted because of the similarity between the two. An expression contains numbers, variables and operators. For example x + 4 2x – 4x^2 5x^2 + 4x -18 and so on… These are … Read more

We’ll see the kind of questions which beg you to stay away from number plugging. Not every question with variables is suitable for number plugging. If there are too many variables, it can be confusing and error prone. Then there are some other cases where number plugging is not suitable. Today we discuss an official … Read more
