Question
The incomes of Priya and Ritu in the current month are
in the ratio of 8:7. The ratio of Priya’s income in the previous month to the current month is 15:16, and that of Ritu is 6:7. If Priya earned Rs. 60,000 last month, then what was Ritu’s income last month?Solution
ATQ,
Let the current month incomes of Priya and Ritu be 8x and 7x, respectively. So, Previous month income of Priya = (8x/16) × 15 = 7.5x Previous month income of Ritu = (7x/7) × 6 = 6x According to the question, 7.5x = 60,000 ⇒ x = 8,000 Therefore, required income = 6x = 6 × 8,000 = Rs. 48,000
