Question

The income of A and B are in the ratio of 6 : 5. If the expenditure of A and B are Rs.12000 and Rs.18000 respectively. The ratio of saving of A and B is 3 : 2, then find the income of A?

• A. 45000
• B. 60000
• C. 61000
• D. 55000

Answer 1

Answer:

B. 60000

Let the income of A be 6x. Let the income of B be 5x. The savings of A = 6x - 12000 The savings of B = 5x - 18000 ⇒ (6x - 12000)/(5x - 18000) = 3/2 ⇒ 12x - 24000 = 15x - 54000 ⇒ 3x = 30000 ⇒ x = 10000 The income of A = 6 × 10000 = 60000
