D Correct answer
Explanation

Cost of 20 = Selling of 25. Let CP of 1 be 1. CP of 20 = 20. SP of 25 = 20, so SP of 1 = 20/25 = 0.8. Loss = 1 - 0.8 = 0.2. Loss% = (0.2 / 1) * 100 = 20%.

AI explanation

Let the cost price of 20 articles and the selling price of 25 articles be 100. This means the cost price of one article is 5 and the selling price of one article is 4, showing a loss of 1 per article. Using the loss percentage formula, (Loss / Cost Price) * 100, the calculation is (1 / 5) * 100, resulting in a 20% loss.
