Hemant sold 10 sarees for a total profit of Rs. 460 and 12 sarees for a total profit of Rs. 144. At what profit per saree should he sell the remaining 20 sarees so that he gets an average profit of Rs. 18 per saree ?


A) Rs. 7.40

B) Rs. 7.60

C) Rs. 7.80

D) Rs.8

E) Rs. 8.5

Answer:

Option B

Explanation:

Total profit required = Rs. $(42\times18)$ = Rs. $756$.

Profit on 22 sarees = Rs. $(460+144)$ = Rs. $604$.

Profit on 20 sarees = Rs. $(756-604)$ = Rs. $152$.

Average profit on these sarees = Rs. $\left(\frac{152}{20}\right)$ = Rs. $7.60$.
