D Correct answer
Explanation

Let cost of 1000g be 100. He sells at 20% profit, so price for 800g (due to 20% less weight) is 120. Profit = 120 - 80 = 40. Profit % = (40/80) * 100 = 50%.

AI explanation

Assume the cost price of 1000g of wheat is Rs. 1000, but the trader gives only 800g, making his actual cost price Rs. 800. He sells this 800g at a 20% profit on the original cost, meaning his selling price for the 800g is 120% of 800, which is Rs. 960. Using the profit percentage formula, his gain is 960 minus 800 equals Rs. 160, and 160 divided by 800 multiplied by 100 yields a 50% gain. The result is 50%.
