If after successive discounts of 20% and 25/4% on the marked price of an article, a trader gets 20% profit on the cost price,then by what percent is the marked price above the cost price?
Choose the correct option:
A) 50%	B) 60%	C) 70%	D) 80%	E) 90%
Let the market price be RS 100. Then after first discount S.P becomes 80 and after another discount it becomes Rs. 75.   so S.P = 75. now with this S.P he has made a profit of 20% and hence the   C.P = (75/120)*100= 
<gadget id="calculator">(75/120)*100</gadget>
<output>125/2 = around 62.5</output>
62.5   so percentage change with respect to market price is= (37.5/62.5)*100   giving 60%   ANSWER:60%
<result>B</result>
