If the cost price of 40 articles is equal to the selling price of 25 articles, what is the % profit or loss made by the merchant?	Choose the correct choice from the following choices: A) 25 % loss B) 25 % profit C) 20 % loss D) 60 % profit E) 75 % profit

Rationale: "let the cost price of 1 article be $ 1 . therefore , cost price of 40 articles = 40 * 1 = $ 40 the selling price of 25 articles = cost price of 40 articles = $ 40 . now , we know the selling price of 25 articles . let us find the cost price of 25 articles . cost price of 25 articles = 25 * 1 = $ 25 . therefore , profit made on sale of 25 articles = selling price of 25 articles - cost price of 25 articles = 40 - 25 = $ 15 . as the profit is in the positive , the merchant has made a profit of $ 15 . therefore , % loss = loss / cp * 100 % loss = 15 / 25 * 100 = 60 % profit . d"
Answer: D
