Question: The 12th but not the final riddle.? There is a barrel with no lid and some wine in it. "This barrel of wine is more than half full," said the Madam. "No it's not," says the man. "It's less than half full." \n\nWithout any measuring implements and without removing any wine from the barrel, how can they easily determine who is correct?

Answer: Well, they could pour exactly half a barrel of wine into the barrel and see whether it overflows.
