A shopkeeper purchases oil at ₹50/litre and sells the same at ₹54/litre. While selling, he gives 900 ml of oil instead of 1 litre. What is his profit percentage?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 20%.
CP of 1 liter = ₹50
SP of 900 ml = ₹54
CP of 900 ml = ₹45 (since 900 ml is 90% of 1 liter, 50 × 0.9 = 45)
Profit = 54 - 45 = ₹9
Profit percentage = (9 / 45) × 100 = 20%
