Question

area of an officer increased by 20%. By what present should the new salary be decreased to restore the original salary.​

Answer 1

Answer:

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.
