A shopkeeper has a fault of 100 g in a 3 kg weight. He sold 3 kg of potatoes to Charu using the same faulty weight for ₹46. The cost price of the potatoes for the seller was ₹12 per kg. How much profit (in ₹) did he earn on the potatoes?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 11.2.
The shopkeeper uses a faulty 3 kg weight.
Actual weight = 3 kg - 100 g = 3 kg - 0.1 kg = 2.9 kg
The shopkeeper bought 2.9 kg of potatoes at ₹12 per kg.
So, total cost price = 2.9 × 12 = ₹34.8
Profit = 46 - 34.8 = ₹11.2
Therefore, the shopkeeper earned a profit of ₹11.2.
