P’s income is 25% more than that of Q. By what percentage is Q’s income less than P’s?

Answer»

Let Q’s income be 100.

P’s income is 25% more than that of Q

∴ P’s income = 100 + 25/100 x 100 = 125

Q’s income is 25 less than that of P

In percentage terms, Q’s income is less than P’s with respect to P’s income is

(P−Q)/P x 100 

= (125−100)/125 x 100 

= 25/100 x 100 

= 20%
