8. The salary of a doctor is increased by 40 %. By
what per cent should the new salary be reduced in
order to restore the original salary?
Answers
Answer:
An increase of 25% salary or 1/4 th must accompany a decrease of 1/(1+4)th or 20% decrease in salary to restore original salary.
Step-by-step explanation:
Let's consider the salary of the officer =100
So, if the salary is increased by 25% then new salary =100+
100
25
×100
=100+25
=125
So, his new salary is 125
To make his salary original 25 must be subtracted from 123, then his salary will be 100 or original salary
So,
% decrease =
125
25
×100
=
5
1
×100
=20%
Hence 20% of his new salary must be deducted so that his salary becomes original salary.
