A shopkeeper bought 1000 kg of rice, a part of which was sold at 10% profit and the remaining at 20% loss; on the whole, the loss was 5%. What is the quantity of rice that was sold at a 20% loss?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 500 kg.
Let total rice = 1000 kg and x kg sold at 10% profit
Let CP per kg = 1
Total CP = 1000
Total SP = 950
1.1x + 800 - 0.8x = 950
⇒ 0.3x = 150
⇒ x = 500 kg
Sold at loss = 1000 - 500 = 500 kg
