## Pigeonhole principle

In this post, we will go through a concept which is typically asked in logical puzzles and brain teasers. Pigeonhole principle may sound a little hard to understand if one just reads the principle, but once you understand the logic, it becomes extremely simple. Read...

## Mass point geometry for CAT 2016

A lot of time, there are questions from triangles become too complicated to visualize and the textbook way of solving them is through the concept of similarity between triangles. In this article, I will introduce the concept of solving these questions through mass...

## Wilson’s theorem for CAT 2016

The concept of negative remainders If the remainder of a mod b is n, the remainder can also be written as (n-b). For e.g. Remainder of 100 divided by 7 is 2 but it can also be written as (2 – 7) = -5. This is called the negative remainder. This is not just useful for...

## Concept: Division method to find HCF

The commonly used methods to find the Highest Common Factor (HCF) or the Greatest Common Divisor (GCD) are the prime factorization method and the simultaneous division method. There is another method (less popular) to find HCF which is extremely useful in certain...
