Amit was given an increment of 20% on his salary. If his new salary is Rs.30600, what was his salary before the increment?
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 )
=> 6x5 = 30600
=> 6 x = 30600× 5
=> x = 30600×56
x = 25,500
