Question

A man's salary was raised by 10% and then reduced by 10%. Find the percentage change in
his salary.
​

Answer 1

Step-by-step explanation:

let the salary be 100 rs

10% increase = 110

then decrease

110×10/100= 11

110-11 = 99

1/100×100 = decrease 1 %

Answer 2

Let the salary be 100

Salary raised by 10%=100+100/10=110

Salary reduced by 10%=110-110×10/100=110-10=99

So, 100-99=1

Percentage change=1×100/100=1%(Ans)
