(
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?

Part 2 by TomM)
well,
suppose i am one of the missionary.
then i would bring one of the cannibals to the other shore, leave him there and would come back to pick another one.
when i'd leave two cannibals in the opposite shore.
i would come back to the first shore again (and alone) and i would pick a missionary with me and would return to the opposite shore.
so there would be one cannibal and a missionary inthe first; and two cannibals and two missionaries in the opposite one
then i'd come back to the first with one of the cannibals, would leave him there and pick up the last missionary and i would take him to the opther shore
thus, we have three cannibals in the first shore and three missionaries in the second
the next is easy
i'd just pick the cannibals one by one and take them to the other shore
