The ratio of monthly incomes of A and B is 4 : 5 and that of their monthly expenditures is 3 : 8. If the income of A is equal to the expenditure of B, then what is the ratio of savings of A and B?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 5 : 2.
Let the income of A and B be 4x and 5x.
Expenditure of A and B be 3y and 8y.
According to the question,
4x = 8y
x = 2y
Income of A and B becomes 8y and 10y
Required ratio = 8y - 3y : 10y - 8y
= 5 : 2.
