Question

4. The salary of a person was increased by 15%. If his salary now is 9,936, what was his
initial salary?​

Answer 1

Step-by-step explanation:

New salary after increase = Rs. 9936

Let x be the Initial salary

Initial salary + 15% of initial salary = New Salary

x+15%(x)=9936

x+(15/100)(x)=9936

x+(3/20)(x)=9936

x+3x/20=9936

(20x+3x)/20=9936

23x=9936*20

23x=198720

x=198720/23

x=8640

Rs. 8640 was his initial salary.
