Question
A boy is supposed to distribute Rs.2400 among his three
friends P, Q and R in the ratio of 4:3:5 respectively, but mistakenly he distributed in the ratio of 5:3:2 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 = [4/(4 + 3 + 5)] × 2400 = Rs.800 Amount received by P mistakenly = [5/(5 + 3 + 2)] × 2400 = Rs.1200 Required difference = 1200 – 800 = Rs.400
