Question
The sum of the monthly incomes of ‘A’, ‘B’ and
‘C’ is Rs. 65000 which is 4 times the monthly income of ‘C’. If ‘A’ spends 55% of his income while ‘B’ spends 80% of his income and the sum of their savings is Rs. 16800, then find the savings of ‘A’.Solution
Monthly income of ‘C’ = 65000/4 = Rs. 16250 Let the monthly income of ‘A’ be Rs. x Therefore, monthly income of ‘B’ = Rs. (48750 – x) According to the question, 0.45x + 0.20(48750 – x) = 16800 Or, 0.25x = 7050 x = 28200 Or, savings of ‘A’ = 0.45x = Rs. 12690
