The question is tricky but not that much.
if you do have in mind the weighted average concept is not difficult
We purchased 5x+6y of rice and this must be 20% more (for having a profit) and the result is the after mixture 7(x+y)
(5x+6y) * 1.2 = 7(x+y)
Doing this simple calculation we will end up with
y = 5x
So
\(\frac{x}{y}=\frac{1}{5}\)
That is our ration and the answer is B
Ask if you do need further explanation
