Brand X coffee costs twice as much as brand Y coffee. If a certain blend is 1/2 brand X and 1/2 brand Y. what fraction of the cost of the blend is Brand X?  Choose the correct option:	A) a. 1/3	B) b. 2/5	C) 3. 2/3	D) 4. 1/5	E) 5. 3/4
Assume Cost of X= Ca = 200 , Cost of Y = Cb=100   The blend contains 0.5 X and 0.55 Y ---&gt; Cost of the blend = Cbl = 0.5*200+0.5*100= 
<gadget id="calculator">0.5*200+0.5*100</gadget>
<output>150</output>
150   Thus fraction of X in the blend= 0.5*200/150 = 2/3.   Answer : 3. 2/3
