Re: Shortcut Tricks to Solve Bank Exams

Hello, I am providing here you the mathematics tricks that one may see in the bank exams as under:

Squaring:
In this simple trick we need to modify the equation and make the units digit zero. After all it is easy to multiply when units digit is zero.

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

Multiplication:
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

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

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
