A dishonest shopkeeper claims to sell salt at a rate of ₹25/kg. The cost price of the salt is ₹25/kg. Not satisfied with this, he tries to make profit by removing 200 gm from each kg. What is the shopkeeper’s gain percentage?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 25%.
The shopkeeper claims to sell 1 kg (1000 gm) but removes 200 gm from each kg
Therefore, the actual quantity sold = 1000 - 200 = 800 gm
The cost price of 1 kg of salt is ₹25
Since he sells 1 kg, the CP for 800 gm = 800/1000 × 25 = Rs. 20
The selling price of 1 kg (as claimed) is ₹25
Profit = SP - CP
⇒ 25 - 20 = Rs. 5
Now,
⇒ Gain% = Profit/CP × 100
⇒ 5/20 ×100 = 25%
Therefore, the shopkeeper’s gain percentage is 25%
