Question
A boy is supposed to distribute Rs.2400 among his three
friends P, Q and R in the ratio of 5:3:4 respectively, but mistakenly he distributed in the ratio of 7:3:2 respectively. Find the difference between amount received by P mistakenly and the amount that P should have actually received.Solution
Amount that should be received by P initially = [5/(5 + 3 + 4)] × 2400 = Rs.1000 Amount received by P mistakenly = [7/(7 + 3 + 2)] × 2400 = Rs.1400 Required difference = 1400 – 1000 = Rs.400
