 The income of A is 80% of B's income, and the expenditure of A is 75% of B’s expenditure. If A’s income is 90% of B's expenditure, then the savings of A is x% more than that of B. What is the value of x? Correct Answer 20

Given : 

The income of A is 80% of B's income 

Expenditure of A is 75% of B's expenditure 

A's income is 90% of B's expenditure 

Calculations :

Let the income of B be '100x' 

So Income of A will be '80x'

For B's expenditure

90% of B's expenditure = A's income 

B's expenditure = 800x/9 

For A's expenditure 

A's expenditure = 75% of B's expenditure 

A's expenditure = 200x/3 

Now savings of A = income of A - expenditure of A 

⇒ 80x - (200x/3)

⇒ 40x/3 

Savings of B = Income of B - Expenditure of B

⇒ 100x - (800x/9)

⇒ 100x/9   

Now 

Required per cent = (40x/3) - (100x/9)/(100x/9) × 100 

⇒ 20% 

∴ Required percentage is 20%
