We all know what factorials (n!) are. They look friendly and helpful but looks can be deceiving, as many quant problems have taught us. Probably it is because that Factorials are simple looking creatures, most students prefer attempting questions based on them rather than on Permutation & Combination or Probability. I will cover P&C and Probability at a later date but in today’s post I would like to discuss some fundas related to factorials, which as a matter of fact form the basis of a large number of P&C and Probability problems.   Some of the factorials that mig

The Covid-19 crisis has forced all of us into lockdown. As a matter of fact, it has given a new meaning to the word home. Some people are adapting to it by watching Netflix series, while others are struggling to kill time. In case you are looking for something different on Netflix, I would strongly recommend Paddleton. I believe it teaches us a lot about life and relationships, which a lot of us are anyway learning thanks to Covid-19. And for those of you, who aren’t Netflix subscribers or just want to get away from the screen sending your friends puzzles are a good idea. You can shar

In this post, we will learn how to solve Logical Reasoning Problems based on coins and matchsticks picking puzzles. To understand how exactly these kinds of puzzles look like, let’s start the post with a very simple example. The method to solve the example will give better insight so as to how to approach these puzzles. Two smart players A and B are playing a coin game in which they can pick up 1, 2, 3 or 4 coins. They have 78 coins and the player who picks the last coin will lose the game. A and B play alternately and A plays the first move. How many coins should A pick at first so h

We usually deal with a lot of equations in the Quant Section equating RHS and LHS. In inequalities, we do have LHS and RHS but these are not equal, any of the following case is possible: LHS >= RHS ; LHS > RHS ; LHS < RHS ; LHS <= RHS  Basic rules of operations on inequality: We can add or subtract same number from both sides with no change in the truth of the inequality. If a > b, then a+k > b+k e.g. If 8 > 6 then 8 + 2 > 6 + 2 and if 9 < 5 then 9 - 3 < 5 - 3 We can multiply or divide both sides with the same number, however the sign will depend

Triangle is the one geometric figure that is the most basic and simple one but. Our first encounter with triangles starts when we are in Pre-school and taught about various shapes through interesting activities. And as soon as we commence stepping up the stairs of our schooling years from 1st till 12th standard, each year we learn something new about triangles. We began this triangular journey with learning about the basics and fundamental properties of the triangle in our 2nd- 3rd std. to concepts of congruency and similarity in our high school. And since triangle and its theory played su
