Question
The sum of the monthly incomes of βAβ, βBβ and
βCβ is Rs. 70000 which is 4 times the monthly income of βCβ. If βAβ spends 40% of his income while βBβ spends 80% of his income and the sum of their savings is Rs. 17000, then find the savings of βAβ.Solution
Monthly income of βCβ = 70000/4 = Rs. 17500 Let the monthly income of βAβ be Rs. x Therefore, monthly income of βBβ = Rs. (52500 β x) According to the question, 0.60x + 0.20(52500 β x) = 17000 Or, 0.4x = 6500 x = 16250 Or, savings of βAβ = 0.6x = Rs. 9750
