Question

Amit was given an increment of 20% on his salary. If his new salary is Rs. 30600 what was his salary before increment?

Answer 1

let the salary before increment = x
increment = 20 % of x 
=> 20 /100 × x 
=> x/5
=> given that if his new salary is  rs. 30600 
=> the new salary is also = x + x/5( the increment in the salary )
=> 6x/5 = 30600
=> 6 x = 30600× 5
=> x = 30600×5/6
x = 25,500 ( ans)
      

Answer 2

Given :

Amit was given an increment of 20% on his salary. New salary is Rs. 30600

To find :

what was his salary before increment?

Solution :

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 = 30,60,000/120

=> x= 25,500.

Hence, his salary before increment was Rs25,500
