Question
The sum of the monthly incomes of ‘A’, ‘B’ and
‘C’ is Rs. 40000 which is 4 times the monthly income of ‘C’. If ‘A’ spends 30% of his income while ‘B’ spends 80% of his income and the sum of their savings is Rs. 18000, then find the savings of ‘A’.Solution
Monthly income of ‘C’ = 40000/4 = Rs. 10000 Let the monthly income of ‘A’ be Rs. x Therefore, monthly income of ‘B’ = Rs. (30000 – x) According to the question, 0.70x + 0.20(30000 – x) = 18000 Or, 0.5x = 12000 x = 24000 Or, savings of ‘A’ = 0.7x = Rs. 16800
