Half Empty or Half Full

A man is the owner of a winery who recently passed away. In his will, he left 21 barrels (seven of which are filled with wine, seven of which are half full, and seven of which are empty) to his three sons. However, the wine and barrels must be split so that each son has the same number of full barrels, the same number of half-full barrels, and the same number of empty barrels. Note that there are no measuring devices handy. How can the barrels and wine be evenly divided?

    Empty two 1/2 barrels into two other 1/2 barrels, resulting in nine full, three 1/2 and nine empty barrels (three full, one 1/2 and three empty barrels each).

  • Very nicely played!
    The RiddleDude came up with this scenario which gives us the same result:

    Two half-full barrels are dumped into one of the empty barrels.

    Two more half-full barrels are dumped into another one of the empty barrels.

    This results in nine full barrels, three half-full barrels, and nine empty barrels.

    Each son gets three full barrels, one half-full barrel, and three empty barrels.

    Great job, you’re today’s winner.
