Afarmer wants to cross a river. he wants to take with him a wolf, a goat, and a cabbage. there is a boat that can fit himself plus either the wolf, the goat, or the cabbage. if the wolf and the goat are alone on one shore, the wolf will eat the goat. if the goat and the cabbage are alone on the shore, the goat will eat the cabbage. how can the farmer bring the wolf, the goat, and the cabbage across the river?

Explanation:

Given that a farmer can take in a boat only  himself plus either the Wolf, the Goat, or the Cabbage.

Since wolf may eat the goat or goat may eat the cabbage, he has to take goat along with him in the I trip to avoid damages to any one.

After leaving goat there he comes back and takes wolf with him. On the other shore he leaves wolf and takes goat and comes back to the starting point. There he leaves goat and takes cabbage and leave it on other side of the shore

Now again he comes back and takes goat with him.

Thus he can safely reach all the three to the next shore.

what he !
