Question

A trader mixes 26 kg of rice at Rs.20 per kg with 30 kg of rice of other variety at Rs.36 per kg and sells the mixture at Rs.30 per kg. His profit percent is:

• A. No profit, no loss
• B. 5
• C. 8
• D. 10

Hint:

Always verify unit costs and total quantities when calculating profit or loss on mixtures to ensure all factors are considered.

Answer 1

The Correct Option is B

Step 1: Calculate the total cost and the total selling price.
\[ \text{Total cost} = 26 \times 20 + 30 \times 36 = 520 + 1080 = 1600 \text{ rupees} \] 
 

\[[ \text{Total selling price} = 56 \times 30 = 1680 \text{ rupees} ]\]

Step 2: Calculate the profit percentage.
\[ \text{Profit} = 1680 - 1600 = 80 \text{ rupees} \] \[ \text{Profit percentage} = \left(\frac{80}{1600}\right) \times 100 = 5% \]
