the concentration of milk in A would be greater because you are mixing some milk (that went from A to B, and taking a part of it back to A) to a lower amount in A.
so what i think is if you are talking about the amount, it would be tha same as in your question but if it is to do with the concentration, there would be a difference (the other way round in your question).
just a try hai.
