A dishonest shopkeeper promises to sell his goods at cost price. However, he uses a weight that actually weighs 18% less than what is written on it. Find his profit percentage.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e .
Assume the cost price (C.P.) per kg = ₹100.
Shopkeeper claims to sell 1 kg at C.P. = ₹100.
But actually, he gives only 100% − 18% = 82% of 1 kg = 0.82 kg
Cost price of 0.82 kg = 100 × 0.82 = ₹82
Selling price (S.P.) = ₹100 (since he charges for 1 kg)
Profit = S.P. − C.P. = 100 − 82 = ₹18
Profit % = 18/82 × 100 =
