Old man - older problem (Posted on 2002-06-28) Difficulty: 2 of 5
(Hopefully this one hasn't been posted it's a really old one I think don't post a solution if you ALREADY know the answer I haven't posted the solution cause I want people to actually try and not just look at the question then giveup right away.)

An old man has a boat and needs to cross the river, the problem is he has three things he needs to get across the river a chicken, a dog, and a sack of grain. He has three problems:

  • His boat can only support himself and one item,
  • The dog can't be left with the chicken, and
  • The chicken can't be left with the grain.

    How does he get across with all three items intact?
