Check answer and explanation
Answer: 20%
Explanation Cost price of 3 oranges = Rs. 5 Cost price of 1 orange = Rs. 5/3 Selling price of 2 oranges = Rs. 4 Selling price of 1 orange = Rs. 4/2 = Rs. 2 Profit per orange = Selling price - Cost price = 2 - 5/3 = (6 - 5)/3 = 1/3 Profit percentage = (Profit/Cost price) × 100% = (1/3) / (5/3) × 100% = 1/5 × 100% = 20% Last verified on 10-03-2026
