Let's consider the salary of the officer =100
So, if the salary is increased by 25% then new salary
=100
+25÷100×100
=100+25
=125
So, his new salary is 125
To make his salary original 25 must be subtracted from 125, then his salary will be 100 or original salary
So,
% decrease = 25/125×100
=1/5×100
=20%
Hence 20% of his new salary must be deducted so that his salary becomes original salary.
