Explanation

At a selling price of Rs. 260, the profit is 260/10 = Rs. 26, so the cost price is Rs. 234. Selling at Rs. 280 gives a profit of Rs. 46, and the gain percentage is 46/234 x 100 = about 19.7%.

AI explanation

The profit at a selling price of 260 is one-tenth of 260, which is 26. Using the formula cost price equals selling price minus profit, the cost price is 260 minus 26, or 234. If he sells it for 280, the gain percentage is ((280 minus 234) divided by 234) times 100, equaling approximately 19.7 percent.
