Question 8

The income of P, Q and R are in the ratio of 5 : 4 : 3 respectively and their expenses are in the ratio of 6 : 5 : 4 respectively. If P saves Rs 4000 out of an income of Rs 10000, then what will be the saving (in Rs) of Q?

Solution

Income of P = Rs. 10,000 and savings of P = Rs. 4,000

=> Expenditure of P = 10000 - 4000 = Rs. 6,000

Ratio of income of P, Q and R = 5 : 4 : 3

=> Income of Q = $$\frac{4}{5}\times10,000=Rs.$$ $$8,000$$

Similarly, expenditure of Q = $$\frac{5}{6}\times6,000=Rs.$$ $$5,000$$

$$\therefore$$ Savings of Q = $$8000-5000=Rs.$$ $$3,000$$

=> Ans - (A)
