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