Let's consider the salary of officer to be 100.
So, If the salary is increased by 25% , then the 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 125 , then his salary will be 125-25 = 100 or original salary.
So, To find percentage of salary which must be decreased we must find that 25 is what percentage of 125 .
So, decrease%
= (25/125) × 100
= 1/5 × 100
= 20%
Answer) 20% of his new salary must be deducted so that his salary becomes Original.

Let Original Salary = 100
After increase = 125/100 x 100 = Rs.125
To restore the original salary, decrease=(125-100)/125 , 25/125 = 1/5 = 20 %
After increase = 125/100 x 100 = Rs.125
To restore the original salary, decrease=(125-100)/125 , 25/125 = 1/5 = 20 %

Please show the increase also , you've directly written 125
She's directly added 25 to 100 actually.
It's okay if the OP gets how she got there.:)
