If selling price of 'x' pens is equal to the cost price of 'y' pens. Then profit percentage = (y-x) x 100 / x<br /><br />E.g 2: The selling price of 12 pens is equal to the cost price of 20 pens. Find the profit percentage?<br /><br />Ans: Percentage profit = (20 - 12) / 20<br /><br />= 8/20<br /><br />= 66.66%.<br /><br />E.g3: If 12 oranges are purchased for Rs. 100 and 10 oranges are sold for Rs. 100. Find the percentage profit / loss ?<br /><br />Ans: Percentage Profit = [(12 - 10) /10]x 100.<br /><br />= (2 /10) x 100<br /><br />= 20 %. In this Below 22nd The example-2 is solved by the formula of 21st (x-y)/y and example-3 is solved by the formula of 22nd (y-x)/x x 100/x,But the question pattern of example-3 is in 21st type so which one is correct??? Whether formula is written wrongly or solved wrongly please tell ????Raji Ammunoreply@blogger.com
