Revanth sold 8 shirts for a total profit of Rs.480 and 12 shirts for a total profit of Rs.160. At what profit per shirt should he sell the remaining 20 shirts so that he gets an average profit of Rs.20 per shirt?
Show answer & explanation
Correct answer: C
Explanation
The correct asnwer si option 3 i.e. Rs 8
Given that
Profit on selling of 8 shirts = Rs 480
Profit on selling of 12 shirts = Rs 160
So, the Profit of 20 shirts = 480 + 160 = Rs 640
The average Profit = Rs 20 per shirt
Total profit on 40 shirts = 20 × 40 = Rs 800
The profit on selling remaining 20 shirts = 800 - 640 = Rs 160
Hence the profit per shirt on selling remaining 20 shirts = 160/20 = Rs 8
