Question

Amit was given an increment 20% on his salary. if his new salary is 30600 what was his salary before the increment

Answer 1

let his salary = X

given increment = 20%

20% of X = 20x/100

given new salary = 30600

X + 20x/100 = 30600

100x + 20x /100 = 30600

120x/100 = 30600

120x = 30,60,000

X = 25,500.

hence before his salary was 25,500

Answer 2

Here is your answer
Increment =20%
New Salary =30600
Salary before increment =30600x100/(100+20)
=3060000/120
=25500

Hope it helps
