I need you to give me the result of the following exercise
There are two two-liter bottles, one with a liter of wine and the other with a liter of water.
Transfer 1/2 of the contents of the water bottle to the wine bottle and mix thoroughly.
The mixture from the wine bottle is then returned to the water bottle, so that the two bottles again have 1 liter of liquid each.
In which of the two bottles was more water left?
How much wine was left in the water bottle?
