Question
Abdul allocates 90% of his income among his wife, son,
and daughter in the ratio of 5:2:1, while saving the remaining amount, which totals Rs. 4,000. From the amount the wife receives, she gives 20% to their son. Calculate the total amount that the son receives.Solution
Let the income of Abdul be Rs. '100y'. Savings of Abdul = 0.1 X 100y = Rs. 10y So, 10y = 4,000 Or, 'y' = 400 Income of Abdul = '100y' = 100 X 400 = Rs. 40,000 Amount received by wife from Abdul = (5/8) X 0.9 X 40,000 = Rs. 22,500 Amount received by son from Abdul = (2/8) X 0.9 X 40,000 = Rs. 9,000 Therefore, required amount = 9,000 + 0.2 X 22,500 = 9,000 + 4,500 = Rs. 13,500
