Doing calculations accurately and quickly plays a big role in cracking the Common Admission Test (CAT). Candidates learn important formulas for CAT and practising shortcuts to avoid complex calculations in CAT 2021.
However, sometimes a complex calculation becomes unavoidable and you have to crunch the numbers to reach a solution. One effective solution to do faster calculations in CAT is Vedic Maths.
What is Vedic Maths?
Vedic Maths is the modern name used for the ancient system of Indian Mathematics. Vedic Maths is a set of 16 Sutras (formulas) and 13 Sub-Sutras (corollaries) that were discovered from the Vedas by Swami Bharati Krishna Tirtha. He developed mathematical principles around these Sutras and Sub-Sutras and published it in 1965 in a book named Vedic Mathematics.
How Vedic Maths Helps Speed Up Calculations in CAT 2021
Vedic Maths is a very important tool to make CAT calculations easy. Being well-versed in the principles of Vedic Maths will help you to understand complex calculations from a different perspective and shorten the time duration of doing calculations. These principles can be quite helpful in your CAT 2021 preparation.
The most use of Vedic Maths in CAT 2021 calculations is in the Quantitative Ability and Logical Reasoning sections. In order to understand how to do it, you must have an understanding of the Sutras. More details have been provided below.

Using Vedic Maths in CAT 2021
For a candidate who has never made use of Vedic maths to solve questions before, it will seem very difficult and confusing at first. This is because it is quite different from the traditional methods of calculation that we are used to. One more reason why it can seem a bit difficult is that sometimes it has very specific uses (For eg. Kevalaih Saptakam Gunyat).
However, with regular practice, it will not only increase your speed of calculations many times but also make them more accurate. And while the methods used in Vedic Maths may seem chaotic and disorganised, each Sutra has an algebraic derivation and proof, which you can study if you are curious.
