The incomes of A and B are in the ratio 6 : 5 and their expenditures are in the ratio 5 : 4 . If each save Rs.2000, then what are their incomes? |
7000 , 8000 8000 , 9000 10000 , 12000 12000 , 10000 |
12000 , 10000 |
* Income - savings = Expenditure Let Income of A & B = 6R & 5R ATQ, ⇒ \(\frac{6R - 2000}{5R - 2000}\) = \(\frac{5}{4}\) ⇒ 24R - 8000 = 25R - 10000 ⇒ R = 2000 Now, Income of A = 6 × 2000 = 12000/-, Income of B = 5 × 2000 = 10000/- |
