Show answer & explanation
Correct answer: B
Answer: 41.17% (approximately).
Because the shopkeeper gives 15% less weight, when he sells 1 kg (1000 g) he actually gives only 850 g.
Take the cost price of 1 kg (genuine) as Rs 100. Then the cost to the shopkeeper for the 850 g he gives = Rs 85.
He makes 20% profit on the labeled 1 kg, so the selling price = 100 × 1.20 = Rs 120.
Profit = 120 − 85 = Rs 35.
Gain percent = (35 / 85) × 100 ≈ 41.176% ≈ 41.17%.
