<gadget id="calculator">20 * 1</gadget>
<output>20</output>
$20   The selling price of 15 articles= cost price of 20 articles = $15.   Now, we know the selling price of 15 articles. Let us find the cost price of 15 articles.   Cost price of 15 articles = 15 * 1= 
<gadget id="calculator">15 * 1</gadget>
<output>15</output>
$15.   Therefore, profit made on sale of 15 articles= Selling price of 15 articles - cost price of 15 articles   = 20 - 15= 
<gadget id="calculator">20 - 15</gadget>
<output>5</output>
$5.   As the profit is in the positive, the merchant has made a profit of $5.   Therefore, % loss= loss/cp * 100   % loss = 5/15 * 100 = 33.33% profit.   33.33% profit
<result>B</result>
