C Correct answer
Explanation

Let CP be the cost price and SP be the selling price. 12 * CP = 10 * SP, so SP/CP = 12/10 = 1.2. The profit is 0.2, which is 20%.

AI explanation

Let the cost price of one article be Re 1, meaning the cost price of 12 articles is Rs 12. Since the selling price of 10 articles equals this cost price, the selling price of one article is 12 / 10 = Rs 1.2. Using the formula for profit percentage, ((1.2 - 1) / 1) * 100, the profit is 20%.
