Answer:

Correct Answer: A

Solution:

Let cost of 1 L milk be Rs. 1. Milk in 1 L mixture in $ A=Rs.\frac{8}{13}L, $ CP of 1 L mixture in $ A=Rs.,\frac{8}{13} $ Milk in 1 L mixture in $ B=\frac{5}{7}L, $ CP of 1 L mixture in $ B=Rs.,\frac{5}{7} $ Milk in 1 L of final mixture $ =( \frac{900}{13}\times \frac{1}{100}\times 1 )=\frac{9}{13}L $ Mean price $ =Rs.\frac{9}{13} $ By the rule of alligation, we have

$ \therefore $ Required ratio $ =\frac{2}{91}:\frac{1}{13}=2:7 $
