Please format your question and follow the guidelines for posting questions in Quant forums. This is NOT a DS question.

Assume Cost of A= Ca = 200 , Cost of B = Cb=100

The blend contains 0.25 A and 0.75 B ---> Cost of the blend = Cbl = 0.25*200+0.75*100= 125

Thus fraction of A in the blend = 0.25*200/125 = 2/5. B is the correct answer.

a. 1/3
b. 2/5
3. 1/2
4. 2/3
5. 3/4

let us use a convenient number, 4
let brand B costs 4; brand A costs 8
one-fourth of A=2 and three-fourths of B is 3
Total cost is 5
The required ratio is 2/5
correct option is B
