Show Answer

Answer:

Correct Answer: D

Solution:

Given, pure milk in container $ =81L $ By replacing $ \frac{1}{3} $ part by water, Remaining milk $ 81-\frac{1}{3}\times 81=81-27=54L $ Again, replacing $ \frac{1}{3} $ part by water.

$ \therefore $ Remaining milk $ =54-\frac{1}{3}\times 54=54-18=36L $ Then, quantity of water at last $ =81-36=45L $

$ \therefore $ Required ratio $ =\frac{36}{45}=\frac{4}{5} $
