For this series of articles, I am assuming CAT 2021 would be the first time you would be attempting CAT, which essentially implies that you are not well versed with the basic ideas behind the Quantitative Aptitude portion. In the latter half of the year, I would move to slightly more advanced topics as by then, you would also have moved to the advanced stage of preparation.

In a series of posts, we are going to cover the basics of some DI/LR topics. The first topic of discussion is Binary Logic. In a binary logic problem, we have people who either speak a true statement or a false statement. These people are divided into three categories: Truth-teller: This person will always speak the truth. All the statements made by this person are true. Liar: This person will always tell a lie.

Big CAT Quiz of the Lockdown

May 18th, 2020 by

Quizzing is an old hobby of mine. I used to quiz a bit in school and a lot in my college years at Kharagpur. As a matter of fact, I even travelled to Indore and Allahabad to participate in quizzes. And back in the day, travel for hobbies didn’t happen by flight but by sleeper class trains. This lockdown gave me an opportunity to conduct couple of live quizzes and I will be lying if I said I didn’t have fun doing them. One of them was based on food and another one on Bollywood. As a matter of fact, I am planning another one on Cricket soon. You can follow me on twitter – I will share

There are some topics in Quantitative Aptitude, like Permutation & Combination,  where you can easily find out the answer and the answer you calculate is there in the options but it turns out to be wrong. And then there are some topics in which you read the question, understand it but cannot even begin solving it. You get stuck at the first step and you have no idea about how to even approach the question. The irritating fact is that you understood the question properly. It happens very frequently with questions on Time Speed & Distance (TSD). I have always been a big advocate of

We all have studied modifiers in our school days. But since it is an optional element in the English language, it is not treated as an important topic. Then why do you need to learn about it now? Well, CAT and other MBA entrance exams often feature questions based on Sentence correction and these questions often contain modifier-based errors.

How to solve questions based on At least n in Set Theory for CAT Exam?

May 2nd, 2020 by

Questions based on Set Theory can get immensely complicated when you add conditions based such as ‘At least 2’ ‘At most 3’ etc. in them. To be honest, you should be absolutely comfortable with questions dealing with 3 sets and know enough to draw the Venn-diagram in case of 4 sets. We dealt with the idea of Minima and Maxima in Set Theory in this post. Beyond that not much is required, at least for the CAT exam. However, there is one particular type of question that can be asked in MBA entrance exams and that is what this short Blogpost is all about. So, let’s start Ques
