Question
A man is supposed to distribute Rs. 2800 among his three
sons, A, B, and C in the ratio of 3:4:7, respectively, but mistakenly he distributed in the ratio of 5:3:2, respectively. Find the difference between amount received by A mistakenly and the amount that A should have actually receivedSolution
Amount that should be received by A initially = [3/(3 + 4 + 7)] × 2800 = Rs. 600 Amount received by A mistakenly = [5/(5 + 3 + 2)] × 2800 = Rs. 1400 Therefore, required difference = 1400 – 600 = Rs. 800
