Profit and Loss is the one concept that we have been studying since class 6th or 7th. It is present in our day-to-day simple transactions from buying vegetables to purchasing expensive jewelry. Everything we purchase today includes profit and loss. Our whole economy from big MNC’s to small retail outlets has been running with the same single intention to make profit. Whatever is being traded in the market has same motive to earn profit. Every seller aims to earn some profit over the product he is willing to sell and from the buyers’ perspective he is earning profit in terms of utility

Questions on clocks (or even calendars) are not really frequent in CAT these days. They used to be really popular few years ago. Having said that, it is always better to understand some of the basic principles and the types of problems that get asked.

This sequence can be used to model or describe various phenomena in the field of biology, mathematics, nature, art etc. The sequence is 0, 1, 1, 2, 3, 5, 8, 13... so on. As we can see, the next no. in the sequence is the addition of previous two numbe

A very common type of question that gets asked in various banking and management entrance exams is based upon the concept of finding out the rank of a word.

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. Best Online Coaching for CAT 2021 I have often seen students struggle with the topic – ‘Permutation & Combination’.

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.

All statements made by this person are false. Alternator: This person always alternates between the truth and the lie. If first statement of this person is true, then se

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
