Question

A man buys 10 kg of rice at Rs. 30 per kg and 15 kg of wheat at Rs. 20 per kg. He sells the mixture at Rs. 28 per kg. What is his profit or loss percentage?

• A. 4% profit
• B. 4% loss
• C. 5% profit
• D. 5% loss

Hint:

Calculate total cost and selling price, then find percentage profit or loss.

Answer 1

The Correct Option is A

- Step 1: Cost price of rice = $10 \times 30 = 300$. Cost price of wheat = $15 \times 20 = 300$.
- Step 2: Total cost price = $300 + 300 = 600$. Total weight = $10 + 15 = 25$ kg.
- Step 3: Selling price = $25 \times 28 = 700$.
- Step 4: Profit = $700 - 600 = 100$.
- Step 5: Profit percentage = $\frac{100}{600} \times 100 = \frac{100}{6} \approx 16.67%$. Recalculate: SP per kg = 28, CP per kg = $\frac{600}{25} = 24$. Profit per kg = $28 - 24 = 4$, so $\frac{4}{100} \times 100 = 4%$.
- Step 6: Option (1) is 4% profit, correct.
