Correct answer is: 7 : 2
Explanation:
Let. C.P. of milk per litre be Re.1
\(\text{Milk in 1 litre of A = }\frac{5}{7} \text{ litre}\)
\(\text{Milk in 1 litre of B }= \frac{8}{13}\)
\(\text{Milk in 1 litre of mixture }= \frac{9}{13} litre\)
\(\text{Therefore, Required ratio}\)
\(= \frac{1}{13} : \frac{2}{91}\)
\(= 7 : 2\)
