The income of P & Q are in the ratio of 7 : 3 and their expenditures are in the ratio of 4 : 1. If each saves Rs. 7500, then what will be the sum of their incomes?
Answer & explanation
Correct answer: option 3
Ratio of Income = 7 : 3
Ratio of Expenditure = 4 : 1
ATQ,
⇒ \(\frac{7R - 7500}{3R - 7500}\) = \(\frac{4}{1}\)
⇒ 7R - 7500 = 12R - 30000
⇒ 5R = 22500
⇒ 1R = 4500
So,
Sum of income of P & Q = 7R + 3R = 10R = 10 × 4500 = 45000
