Across the River

Logic Level 1

A farmer has a cabbage, a goat, and a lion. He needs to get all three of them across a river, but there is only enough room in his boat for one at a time as well as himself. If he leaves the goat and the cabbage together on one shore, the goat will eat the cabbage. If he leaves the lion with the goat, the lion will eat the goat.

He can take them to and from either shore as many times as he needs.

If he wants to get all three of them across to the other side, what animal should he take first?

He should take the goat first He should take the lion first It's impossible for him to get all three of them across the river He needs to get a bigger boat

The lion can eat the goat and the goat can eat the cabbage,

First , take the $\boxed{goat}$ to the other side of the river.

Then, take the lion to other side of the river and again take back the goat.

Then, take the cabbage to the other side of the river.

Finally, take the goat to the other side of the river.

In this way all of them will be safe.

If he takes anything else than the goat, something will eat something.

(To complete the problem: The goat is left on the far shore, the farmer goes back for the cabbage on the first shore. The farmer drops off the cabbage at the far shore and picks up the goat and carries the goat back with him to the first shore. Drops the goat back off at the first shore while he picks up the lion. Drops the lion at the far shore (Both Lion and Cabbage are now at the far shore.) Then goes back for the goat. Considering the goat did not walk away.

If you take the goat first, then come back and take the lion, bring back the goat, take the cabbage, then come back and take the goat, they all live.

that is quite easy to find. cz the lion will not eat the cabbage.

so, if he takes the goat at first then there will be no collision among the lion and cabbage.and also the goat will not be able to eat cabbage.

so, after taking the goat he will find everything safe.
