C Correct answer
Explanation

Cost price of 1kg of mix = (10+15)/2 = 12.5. Selling price = 15. Profit = 15 - 12.5 = 2.5. Profit percentage = (2.5 / 12.5) * 100 = 20%.

AI explanation

Assume 1 kg of each onion lot is mixed, making the total cost 10 + 15 = 25 rupees for 2 kg. The mixture is sold at 15 rupees per kg, so the total selling price for 2 kg is 30 rupees. The profit is 30 - 25 = 5 rupees. Using the profit percentage formula, (5 / 25) * 100 = 20% profit.
