The incomes of two persons P and Q are in the ratio 5 : 6. If each of them saves ₹ 200 per month, the ratio of their expenditures is 3 : 4. Find the income of Q.

₹600

                   P   :   Q

Income        5   :   6

Expenditure  3   :   4

⇒ Savings = (6 - 4)units or (5 - 3)units = Rs. 200

⇒ 2 units = Rs. 200

⇒ 1 unit = Rs. 100

⇒ Income of Q = 6 x 100 = Rs. 600.
