The incomes of two individuals, 'X' and 'Y', are in the
ratio 6:9. 'X' spends 75% of his income, while 'Y' spends 80% of his income. Find the ratio of their savings.Solution
ATQ,
Let the incomes of 'X' and 'Y' be Rs. 6m and Rs. 9m respectively. Savings of 'X' = 6m - 6m × 0.75 = 6m - 4.5m = Rs. 1.5m Savings of 'Y' = 9m - 9m × 0.8 = 9m - 7.2m = Rs. 1.8m Required ratio = (1.5m : 1.8m) = 15 : 18 = 5 : 6
