D Correct answer
Explanation

The shopkeeper uses 800g instead of 1000g. Gain = (Error / True Value - Error) * 100 = (200 / 800) * 100 = 25%.

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 800) divided by 800) multiplied by 100. This simplifies to (200 divided by 800) multiplied by 100, resulting in a gain of 25 percent.
