A store owner sells goods at the cost price but uses a 750 g weight in place of a 1 kg weight. What is the gain percentage?

A. 33.33%✓ Correct Answer
B. 38.33%
C. 66.66%
D. 25%

💡 Solution & Explanation

The buyer pays for 1,000 g but receives only 750 g. So the seller gains 250 g on every 750 g actually given. Gain % = (250 ÷ 750) × 100 = 33.33%. Dividing by 1,000 instead gives 25%, which is wrong because the cost is for the 750 g handed over.
