Bernhard's Beer
Bernhard brought 5 barrels of beer and 1 barrel of wine to the market in October. Each was marked with the number of gallons that the barrel contained as shown in the illustration. He sold a quantity of beer to one man and twice the quantity to another, but because it was the Oktoberfest season, no one would buy the barrel of wine.
Can you say which barrel contains the wine? The barrels were sold unopened, just as they were, without any changes made to their contents.
