A dishonest shopkeeper promises to sell his goods at cost price. However, he uses a weight that actually weighs 39% less than what is written on it. Find his profit percentage.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 63% .
He gives only 61% of the weight (100% - 39%) but takes full price.
Profit% = (Gain / Cost) × 100
Let cost price of 1 kg = ₹100
He gives only 0.61 kg, costing him ₹61
Sells at ₹100 → profit = 100 - 61 = ₹39
Profit% = (39 / 61) × 100 ≈ 63.93% or 63% .
