Once upon a time a farmer went to a market and purchased a wolf, a goat, and a

cabbage. On his way home, the farmer came to the bank of a river and rented a

boat. But crossing the river by boat, the farmer could carry only himself and a

single one of his purchases: the wolf, the goat, or the cabbage.If left unattended

together, the wolf would eat the goat, or the goat would eat the cabbage.The

farmer's challenge was to carry himself and his purchases to the far bank of the

river, leaving each purchase intact. How did he do it?

Respuesta :

Given that the wolf would eat the goat, the goat would eat the cabbage but the wolf wouldn't eat the cabbage.

So, leave the wolf and cabbage behind (at side 1) and take the goat to the other side (side 2) of the river.

Then, come back with the empty boat from side 2 to side 1.

Take the wolf (or the cabbage) from side 1 to side 2 of the river.

Now, observe that, the goat is already on side 2, and the wolf and the goat can't be on the same side as the wolf would eat the goat, So, leave the wolf on side 2 and come back with the goat from side 2 to side 1.

Leave the goat on side 1 and take the cabbage from side 1 to side 2.

Now, come back with the empty boat from side 2 to side 1 and take the goat from side 1 to side 2.

In this way, the farmer can carry himself and his purchase to the other side of the river.
