A retailer has 250 kg of rice a part of which he sells at 10% profit. The remaining quantity of rice is of low quality and he sold it at 5% loss. Overall he made a profit of 7%. The quantity of rice sold at 5% loss is :

65 kg

75 kg

50 kg

100 kg

✅ Correct Option: 3

Let $x$ kg sold at 10% profit, $(250-x)$ kg at 5% loss. Take CP $=$ Rs 1/kg.

Profit $=0.1x-0.05(250-x)=0.15x-12.5$ .

For 7% overall profit: $0.15x-12.5=17.5\Rightarrow x=200$ .

Quantity at 5% loss $=250-200=50$ kg.
