In bank exam and any other entrance exam all the maths tricks that will speed up your calculation speed. Maths is a subject in CAT and IBPS exam. The only best book for the Numerical Aptitude is R.S AGGARWAL.

List of Cool Maths Tricks
1. Squaring

In this simple trick you need to modify the equation and make the units digit zero. After all it is easy to multiply when unit’s digit is zero.

For example - Find square of 43
= (43+3) × (43-3) + (3×3)
=(46×40) + 9
= (460×4) + 9
= 1840 + 9 = 1849

Detailed post on Multiplication technique (Multiplication of 3 digit numbers)

Read quick Multiplication technique without using complicated Vedic maths
Multiplication with 5
Simply multiply the number by 10 and then divide it by 2.
For example 99×5= 990/2= 495

Multiplication with 4
Multiplication with 9
Multiplication with 6

Multiplication with 99
Multiply the number with 100 and then minus same number from the result. Let's take an example

Questions related to mixtures can be easily solved by allegation method. By using alligation you can wide arrange of maths questions. Let me explain this with a simple example


Price of wine is $60 per litter. If Samuel is adding water with and selling the mixture for $40 per litter. Profit margin remains same. What is the ratio of water and wine in the mixture?

Square root

Best method to find square root of large numbers is by dividing the number into parts. Let's take an example
Find square √ 1936
√ 1936 = √ 4 × √ 484 = √ 4 × √ 4 × √ 121 = 2×2×11 = 44

Time and Work

Every question in in time and work chapter can be solved easily by finding efficiency of workers or subject (such as pipes).

For example - A takes 10 days to complete a job. B takes 20 days to complete the same job. In how many days they will complete the job if they work together ?

A's efficiency = 100/10 = 10% per day
B's efficiency = 100/20 = 5% per days

A and B can do 15% of the work in a day if they work together. So they can do the whole job in 100/15 = 6.66 days or 6 days and 18 hours.

Profit and Loss

In case of profit
25% of Cost Price (1/4 of CP) = 20% of Selling Price (1/5 of SP)
Similarly 1/3 of CP = 1/2 of SP

In case of loss
25% of Selling Price (1/4 of SP) = 20% of Cost Price (1/5 of CP)
Similarly 1/3 of SP = 1/2 of CP

Profit and loss practice questions


That's the most important technique. This is not a secret that every successful candidate is using this technique during exams.

Example - 112 × 92
Simply 112 × 9 = 1008
Add a zero 10080 and then add 224 to 10080.
Answer is 10304

You need to do calculations in your brain. Without using any paper. You need to divide complex calculations in parts and solve it in your brain without paper. That's how toppers do complex calculations during exams.

It will be difficult for you to use this method but with practice, you will be able to do any complicated calculation within seconds.
