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?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 20.
Let B's expenditure = 100
A's income = 90
A's expenditure = 75
B's income = 90/0.8 = 112.5
A's savings = 90 - 75 = 15
B's savings = 112.5 - 100 = 12.5
x = (2.5/12.5) × 100 = 20
