A Correct answer
Explanation

The trader buys 10 kg at 400/kg (total 4000). Half (5 kg) sold at 20% loss: 5 * 400 * 0.8 = 1600. Remaining 5 kg sold at 10% profit: 5 * 400 * 1.1 = 2200. Total revenue is 3800, which is a 200 loss on 4000, or 5% loss.

AI explanation

The total cost price for the 10 kg of tea is 10 multiplied by 400, equaling 4000. He sold 5 kg at a 20 percent loss for 1600, and the remaining 5 kg at a 10 percent profit for 2200. The total selling price is 3800, so the loss is 4000 minus 3800 equals 200. Using the loss percentage formula, the net loss is (200 divided by 4000) multiplied by 100, resulting in a 5 percent loss.
