    A shopkeeper bought 80 kg of sugar at the rate of Rs. 13.50 per kg. He mixed it with 120 kg of sugar costing Rs. 16 per kg. In order to make a profit of 20%, he must sell the mixture at

    A) Rs. 18 per kg     

    B) Rs. 17 per kg

    C) Rs. 16.40 per kg 

    D) Rs. 15 per kg

    Correct Answer: A

    Solution :

    CP of 200 kg of sugar \[=Rs.(80\times 13.50+120\times 16)\] \[=Rs.\text{(}1080+1920\text{)}\] \[=Rs.\,3000\] \[\therefore \] CP of 1 kg of sugar \[=\frac{3000}{200}=Rs.\,15\] \[\therefore \] To gain 20% SP \[=15\times \frac{120}{100}\]                         \[=Rs.\,18\,\text{per}\,\text{kg}\]
