A trader gives 8% discount on the marked price of an article and gives 3 articles free for buying 25 articles. He gains 15% in the entire transaction. Assuming a customer pays for 25 articles, the marked price of the article is what percentage more than its cost price?

A38%
B40%
C25%
D50%

Correct answer: B

Explanation

Let the cost price be 100 each. 28 articles cost 2800. Total sale amount for 15% gain = 2800 × 1.15 = 3220. This comes from selling 25 articles at 92% of the marked price, so marked price = 3220 ÷ (25 × 0.92) = 140, which is 40% more than cost price.
