Brand A coffee costs twice as much as brand B coffee. If a certain blend is 1/4 brand A and 3/4 brand B. what fraction of the cost of the blend is Brand A?	Choose the most appropriate option:	A) 1/3	B) 2/5	C) 1/2	D) 2/3	E) 3/4
Assume Cost of A= Ca = 200 , Cost of B = Cb=100   The blend contains 0.25 A and 0.75 B ---&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 A in the blend= 0.25*200/125 = 2/5. 2/5 is the correct answer.
