C Correct answer
Explanation

Total cost = 20 * 48 = 960. Profit on 8 dozen = 8 * 48 * 0.10 = 38.4. Profit on 12 dozen = 12 * 48 * 0.20 = 115.2. Total profit = 153.6. Profit percentage = (153.6 / 960) * 100 = 16%.

AI explanation

Using the weighted average method for profit percentages, the overall profit is (8 times 10 + 12 times 20) divided by 20. This calculates to (80 + 240) divided by 20, resulting in 320 divided by 20. The total profit percentage for the transaction is 16.
