(
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?
I haven't done this problem before, so.
d - dog, c - chicken, g - grain, m - man
Obviously we start with the dog, the chicken, and the grain.
D C G M (river)
If we were to take the dog the chicken would be left witht he grain. If we were to take the grain the dog would be left with the chicken. Thusly, we take the chicken.
D G (river) C M
We go back and take the dog.
G (river) D C M
Upon putting the dog on the other side of the river, we take the chicken. (This is assuming that the man can stop the dog from eating(?) the chicken for long enough to grab it.)
G C M (river) D
Then we take the grain. The dog can be left alone with the grain.
C (river) D G M
Then we go back and take the chicken.
(river) D C G M
And it is solved.
Simple. (Long)
