A) 102%  B) 90%  C) 120%  D) 85%  E) 95%
Easiest thing to do: Assume that price is 100   Price at the end of yr 1: 100+ 20 = 120   Price at the end of year 2 = 120 - 120*0.25 = 120*0.75= 
<gadget id="calculator">120*0.75</gadget>
<output>90</output>
90   Hence required answer= (90/100)*100= 
<gadget id="calculator">(90/100)*100</gadget>
<output>90</output>
90%   Answer is 90%.
