Question
The income of 'X' is 25% more than that of 'Y'. 'X' and 'Y'
save 30% and 15% of their incomes respectively. If the difference between their expenditures is Rs. 660, find the amount saved by 'X'.Solution
ATQ,
Let the income of 'Y' be Rs. '100n'
Income of 'X' = 1.25 Γ 100n = Rs. '125n'
Expenditure of 'X' = 0.7 Γ 125n = Rs. '87.5n'
Expenditure of 'Y' = 0.85 Γ 100n = Rs. '85n'
So, 87.5n - 85n = 660
Or, 2.5n = 660
Or, 'n' = 264
Savings of 'X' = 125n - 87.5n = 37.5n = 37.5 Γ 264 = Rs. 9,900
