A shopkeeper marks up the price of the oil by 40% and uses a faulty machine which measures 15% less. If the shopkeeper gives a discount of 32%, the profit/loss percentage is:
A.12% Profit✓ Correct
B.18% Loss
C.15% Loss
D.25% Profit
Explanation
Let cost price = 100. Marked price = 140. After 32% discount, selling price = 140 × 0.68 = 95.2. The machine measures 15% less, so shopkeeper gives only 85g per 100g. Effective SP per 100g = 95.2/0.85 ≈ 112. So profit ≈ 12%.
