A man buys 15 identical articles for a total of Rs. 15. If he sells each of them for Rs. 1.23, then his profit percentage is:

Explanation

Total cost price (CP) of 15 articles = Rs. 15 Cost price per article = 15 / 15 = Rs. 1 Selling price (SP) per article = Rs. 1.23 Now, calculate the profit per article: Profit per article = Selling price - Cost price = 1.23 - 1 = Rs. 0.23 Profit percentage = (Profit per article / Cost price per article) × 100% Profit percentage = (0.23 / 1) × 100% = 23% Therefore, the profit percentage is 23%.
