Answer

C

Explanation

By Statement -I
`M:W=27:13`
So, in 80 litres of mixture contain
Quantity of milk `=27/40xx80=54` litres
Water `=13/40xx80=26` litres
By Statement - II
If 16 litres of mixture replaced by equal quantity of milk. Then in new mixture
Quantity of mikl `=4/5xx80=64` litres
Quantity of water `=1/5xx80=16` litres
Again by statement - I
Before mixing water,
Milk is 54 litres and water is 18 litres
Statement - II Before mixing milk Milk is 48 litres and water in mixture, `=3:1`
Quantity of milk `=3/4xx80=60` litres
Concept Ratio of milk to water always same in the mixture. It doesn't depend on quantity of mixture drawn.
