A farmer must cross a river with a wolf, a goat, and a cabbage.
The boat fits only him + one item.
Wolf eats goat. Goat eats cabbage.
How does he get all three across?

Question

Accepted Answer

Take goat over. Return alone. Take wolf over, bring goat back. Leave goat, take cabbage over. Return alone. Take goat over. — The trick is the return trip with the goat. We assume each crossing must be forward; the puzzle hinges on going backward at exactly the right moment.
