Question

A man got a 10%increase in his salary.if his new salary is rs 1 ;54;00;find his original salary.

Answer 1

Hope this will help.

Suppose the original salary of man is x.

Then new salary will be x + 10% of x.


But the new salary is 15,400 rs.

Thus 15,400= x + 10% of x
15,400= x + 10x/100
15,400= x + x/10
Taking L.C.M. on RHS
15,400=10x + x / 10
15,400 × 10 = 11x

Therefore x = 14,000

Thus the original salary of man is 14,000Rs.
