Sam purchased 20 dozens of toys at the rate of Rs. 375 per dozen. He sold each one of them at the rate of Rs. 33. What was his percentage profit?

Given

• 20 dozens ⇒ 20 × 12 = 240 toys
• Cost per dozen = Rs. 375 ⇒ Total cost = 20 × 375 = Rs. 7,500
• Selling price per toy = Rs. 33 ⇒ Total revenue = 240 × 33 = Rs. 7,920

Compute profit and percent
Profit = 7,920 − 7,500 = Rs. 420Profit% = 420 ÷ 7,500 × 100 = 5.60%

Final Answer: Percentage profit = 5.60%.
