In order to keep the constant, the same and not vary there must be an indirect or inverse relationship to always maintain the value of k.
Thus both P and V are inversely related to each other.
Lets suppose his initial weight was 60 kilograms
A gain of 20% would make his new eight 60 + 20*60/100
= 60 + 12
= 72 kg
he lost 25% of this:-
= 72 - 25 * 72/100 = 54 kg
This = (54/60) * 100 = 90% of his beginning weight Answer
