Question

on increasing the salary of a man by 12% his salary in increased by rs2316. what was his original salary?

Answer 1

Let the original salary of the man be y.

Increment = 12%
New salary = y+12% of y
= y+12y/100
=112y/100

Now, Original salary+Increased amount = New salary
Therefore, y+2316 = 112y/100
or 100(y+2316) = 112y
or 100y+231600 = 112y
or 112y - 100y = 231600
or 12y = 231600
or y = 231600/12 = 19300

Hence, the original salary of the man is Rs. 19,300

Hope that helps
