Brand X coffee costs twice as much as brand Y coffee. If a certain blend is 1/4 brand X and 3/4 brand Y. what fraction of the cost of the blend is Brand X?	Choose the correct option:	A) a. 2/5	B) b. 1/5	C) 3. 1/2	D) 4. 2/3	E) 5. 3/4
Assume Cost of X= Cx = 200 , Cost of Y = Cy=100   The blend contains 0.25 X and 0.75 Y ---&gt; Cost of the blend = Cbl = 0.25*200+0.75*100= 
<gadget id="calculator">0.25*200+0.75*100</gadget>
<output>125</output>
125   Thus fraction of X in the blend= 0.25*200/125 = 2/5.   a. 2/5nswer : a. 2/5
<result>A</result>
Brand X coffee costs twice as much as brand Y coffee. If a certain blend is 1/4 brand X and 3/4 brand Y. what fraction of the cost of the blend is Brand X?
