C Correct answer
Explanation

Cost of 25 = Selling of 20. Let CP of one be 1. 25 = 20 * SP, so SP = 25/20 = 1.25. Gain = 0.25, which is 25%.

AI explanation

Let the cost price of one article be 1 rupee, so the cost price of 25 articles is 25 rupees. Since the selling price of 20 articles equals 25 rupees, the selling price of one article is 25 divided by 20, which equals 1.25 rupees. Using the profit percentage formula, (1.25 minus 1) divided by 1 and multiplied by 100 gives a gain of 25%. The result is 25%.
