Explanation

Profit = (Error / (True Value - Error)) * 100. Error = 100g. True value = 1000g. Profit = (100 / 900) * 100 = 100/9 = 11.11%.

AI explanation

Use the formula for profit percentage when a faulty weight is used: ((True Weight - False Weight) / False Weight) multiplied by 100. The trader measures 900 grams instead of 1000 grams, so the calculation is ((1000 - 900) / 900) * 100. This equals (100 / 900) * 100, which results in a gain of 11 (1/9)%.
