Question:

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?

Options:

7000 , 8000

8000 , 9000

10000 , 12000

12000 , 10000

Correct Answer:

12000 , 10000

Explanation:

* 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/-
