Question
The sum of the monthly incomes of ‘A’,
‘B’ and ‘C’ is Rs. 50000 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. 15000, then find the savings of ‘A’.Solution
Monthly income of ‘C’ = 50000/4 = Rs. 12500 Let the monthly income of ‘A’ be Rs. x Therefore, monthly income of ‘B’ = Rs. (37500 – x) According to the question, 0.45x + 0.20(37500 – x) = 15000 Or, 0.25x = 7500 Or, savings of ‘A’ = 0.45x = Rs. 13500
