Answer:
If his salary is now is Rs 9936, what was his initial salary? Rs. 8640 was his initial salary.
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.
Answer:
Let his initial salary be x.
According to the problem:
x+(15/100)x = 9936
=> x+15x/100=9936
=>(100x+15x)/100=9936
=>115x=9936x100=993600
=>x=993600/115=8640
Answer: The person's initial salary was 8640 Rs.
TO CHECK:
15/100x9936=1296
9936-1296=8640 Rs.
