Question
Ramesh spends 40% of his income and divides the
remaining income among his wife and children (a daughter and a son) in the ratio of 3:4, respectively. If the ratio of the amount received by his daughter to that by his son is 4:3. Find the money spent by Ramesh if his son gets Rs. 3,600.Solution
ATQ, Let the income of Ramesh be Rs. '100c'. Money spent by Ramesh = 0.4 × 100c = Rs. '40c' Money received by his wife = (3/7) × (100c - 40c) = Rs. '30c' Money received by his children = (4/7) × (100c - 40c) = Rs. '60c' Money received by his son = (3/4) × 60c = Rs. '45c' ATQ, 45c = 3600 Or, 'c' = 80 Therefore, money spent by Ramesh = Rs. '40c' = Rs. (40 × 80) = Rs. 3,200
