Haroon purchased 30 kg of wheat at the rate of Rs. 11.50 per kg and 20 kg of wheat at the rate of 14.25 per kg. He mixed the two and sold the mixture. Approximately what price per kg should be sell the mixture to make 30% profit?
Correct answer: D. Rs. 16.30
- A. Rs. 14.80
- B. Rs. 15.40
- C. Rs. 15.60
- D. Rs. 16.30
- E. Rs. 18.20
Explanation
The total cost is 30 kg x Rs. 11.50 per kg + 20 kg x Rs. 14.25 per kg = Rs. 345 + Rs. 285 = Rs. 630 for 50 kg. Cost per kg is Rs. 630 / 50 kg = Rs. 12.60 per kg, and a 30% profit requires Rs. 12.60 x 1.30 = Rs. 16.38 per kg, approximately Rs. 16.30 per kg among the options. The likely wrong choice is Rs. 15.60, which comes from using an incorrect average cost.
