The cost price of 6 articles is equal to the selling price of 10 articles. Find the gain or loss per cent.

  1. A. 40% loss
  2. B. 60% loss
  3. C. 60% gain
  4. D. 40% gain

Correct Answer: A. 40% loss

Explanation

Given 6 \times CP = 10 \times SP \Rightarrow \frac{SP}{CP} = \frac{6}{10} = \frac{3}{5}. Since SP is less than CP, there is a loss. Loss \% = \frac{5-3}{5} \times 100 = 40\%.
