A shopkeeper sells goods at 82% loss on cost price but uses 28% less weight. What is his percentage profit or loss?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 75% loss.
Let the CP for 1 kg = 100
Since the shopkeeper uses 28% less weight, the weight used = 1 - 0.28 = 0.72 kg
CP for 0.72 kg = 100 × 0.72 = 72
SP = 100 - 82% of 100 = 18
⇒ Loss Percentage = [(72 - 18)/72] × 100 = (54/72) × 100 = 75%
