The incomes of P and S are in the ratio 7 : 6 and their expenditures are in the ratio 6 : 5 . If each save Rs.2500, then what are their incomes? |
75000 , 85000 80000 , 90000 17500 , 15000 120000 , 140000 |
17500 , 15000 |
* Income - savings = Expenditure Let Income of P & S = 7R & 6R ATQ, ⇒ \(\frac{7R - 2500}{6R - 2500}\) = \(\frac{6}{5}\) ⇒ 35R - 12500 = 36R - 15000 ⇒ R = 2500 Now, Income of P = 7 × 2500 = 17500/-, Income of S = 6 × 2500 = 15000/- |
