C Correct answer
Explanation

Let CP be cost price and SP be selling price. 11 * SP = 13 * CP, so SP/CP = 13/11. Gain = SP - CP = 13 - 11 = 2 units. Gain percentage = (2/11) * 100 = 200/11 = 18 2/11 percent.

AI explanation

Using the formula for gain percentage when selling price of x articles equals cost price of y articles, the gain percentage is calculated as ((13 - 11) / 11) multiplied by 100. This equals 200 divided by 11, which can be written as the mixed fraction 18 2/11%. The result is 18 2/11%.
