C Correct answer
Explanation

The shopkeeper sells 900g but charges for 1000g. Gain = (Error / True weight - Error) * 100 = (100 / 900) * 100 = 100/9 = 11.11%.

AI explanation

Using the formula for gain percentage when a false weight is used, Gain Percentage equals (True Value minus False Value) divided by (False Value) multiplied by 100. The shopkeeper gives 900 grams instead of 1000 grams, so the gain is calculated as (1000 minus 900) divided by 900 multiplied by 100. This simplifies to 100 divided by 900 multiplied by 100, which equals approximately 11.11%.
