As you could see from the various responses posted for this Mind Bender … there is clearly more than one way to share the Wine Barrels between the three brothers.
However, the challenge this time was to come up with the solution that was the most elegant in its simplicity.
To do that, you needed to pour four of the half barrels together, to make two more full ones.
Then, you’ll find you have:
* 9 full barrels,
* 3 half barrels, and
* 9 empty barrels.
Each of these combinations can now be divided by three.
