let x be the capacity of cask
ratio of milk to total solution= [x(1-E/x)^2]/x=16/(16+9)
= 1-E/x=4/5
therefore x=5E

Answer is Cannot be determined.
As we do not know the number of iteration that are done to get the final result.

Lets consider the following example,

If the cask is of 25 litres and 9 litres are replaced with water, we will get the final result.

If we take 5 litres out, then fill water and then again 5 litres out and fill with water, we again get the final result

So, answer is cannot e determined
