Question

If a's salary is less than 25% of b's salary, then how much percent of salary of a is higher than a's salary?

Answer 1

A/Q 
100+100 of 20% = 100 + 20
120 of x% = 100
6x / 5 =100
x = 83.33
Reduced % = 100 - 83.33 
= 16.67%

Answer 2

Given....
100 + 100 of 20% = 100+20
=> 120 of x% = 100
=> 6x/5 = 100
=> x = 83.33

Therefore,
Reduced %
=100 - 83.33
=16.67%


Hope this helps.
