C Correct answer
Explanation

Cost price of 1 orange = 10/11. Selling price of 1 orange = 11/10. Profit = (11/10 - 10/11) / (10/11) = (121-100)/110 * 11/10 = 21/110 * 11/10 = 21/100 = 21%.

AI explanation

The cost price of one orange is 10 divided by 11, which equals Rs 0.909, and the selling price of one orange is 11 divided by 10, which equals Rs 1.1. Using the gain percentage formula, Gain Percentage equals (Gain divided by Cost Price) multiplied by 100. Substituting the values gives a gain of 0.191 divided by 0.909, resulting in approximately a 21% gain.
