A Correct answer
Explanation

Gain = (True weight - False weight) / False weight * 100 = (1000 - 900) / 900 * 100 = 100 / 900 * 100 = 100/9%.

AI explanation

Using the direct formula for faulty weight profit percentage, Gain Percentage equals ((True Weight minus False Weight) divided by False Weight) multiplied by 100. Substituting the values for a kilogram, we get ((1000 minus 900) divided by 900) multiplied by 100. This simplifies to (100 divided by 900) multiplied by 100, resulting in a gain of 100/9 percent.
