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 ?
Answer & explanation
Correct answer: option 4
A : B
Income 4 : 5
Expenditure 3 : 8
Given, 4R₁ = 8R₂,
R₁ = 2R₂ = R
Monthly income of A = 8R, B = 10R
Expenditure of A = 3R, B = 8R
Savings = Income - Expenditure
Ratio A : B = 5 : 2
