A Correct answer
Explanation

The vendor sells 960g but charges for 1000g. Profit = (1000 - 960) / 960 = 40 / 960 = 1 / 24 = 0.04166... or 4.17%.

AI explanation

The vendor gives the customer only 960 grams while charging for a full 1000 grams at the cost price. His profit in terms of product is 40 grams for every 960 grams he actually dispenses. Using the profit percentage formula of (error divided by true weight) multiplied by 100, the calculation is (40 divided by 960) multiplied by 100, resulting in a 4.17% profit.
