Question
The sum of the monthly incomes of βAβ, βBβ and
βCβ is Rs. 85000 which is 4 times the monthly income of βCβ. If βAβ spends 75% of his income while βBβ spends 80% of his income and the sum of their savings is Rs. 18900, then find the savings of βAβ.Solution
Monthly income of βCβ = 85000/4 = Rs. 21250 Let the monthly income of βAβ be Rs. x Therefore, monthly income of βBβ = Rs. (63750 β x) According to the question, 0.25x + 0.20(63750 β x) = 18900 Or, 0.05x = 6150 x = 123000 Or, savings of βAβ = 0.25x = Rs. 30750
