If the cost price of 20 articles is equal to the selling price of 25 articles, what is the % profit or loss made by the merchant? Pick one:	A) 25% loss	B) 20% loss	C) 25% Profit	D) 20% Profit	E) 5% profit
Let the cost price of 1 article be Rs. 1.   Therefore, cost price of 20 articles = 20 * 1 = Rs. 20   The selling price of 25 articles = cost price of 20 articles = Rs. 20.   Let us find the cost price of 25 articles.   Cost price of 25 articles = 25 * 1 = Rs. 25.   Therefore, profit made on sale of 25 articles = Selling price of 25 articles - cost price of 25 articles   = 20 - 25 = -Rs. 5.   Because the profit is in the negative, the merchant has made a loss of Rs.5.   Therefore, % loss = Loss /Cost Price∗100   % loss = 5/25∗100 =20% loss.   Answer : 20% loss
