Problem: You have two glasses each filled with exactly the same amount of liquid. One containing water, the other, wine.

First take a teaspoon of water from the water glass and pour it into the wine glass. Next stir the wine and water until well mixed. Then take a teaspoon of the water and wine mixture and pour it into the glass of water.

The question is: is there more/less/equal wine in the water glass than water in the wine glass ?
