Suppose you have 14 full bottles of wine and 10 empty bottles to be distributed evenly among three people. Seven of the full bottles are standard size (let's say 1 liter), and the other seven full bottles are double size (2 liters). Half of the empty bottles are standard size; the other five are double size bottles. Divide the bottles into three groups that contain the same volume of wine and the same number of bottles of each size.
