Question

Крестьянину нужно переправить через реку волка, козу и капусту. Но лодка такова, что в ней может поместиться только крестьянин, а с ним — или только волк, или только коза, или только капуста. Но если оставить волка с козой без крестьянина, то волк съест козу, а если оставить козу с капустой, то коза съест капусту. Как быть?

Answer 1

Вначале крестьянин опять-таки перевозит козу. Но вторым он не обязательно должен забирать волка! Можно взять капусту, отвезти ее на другой берег, оставить там и вернуть на первый берег козу. Затем перевезти на другой берег волка, вернуться за козой и снова отвести ее на другой берег.

Answer 2

Сначала нужно переправить козу, потом вернуться за волком, отвезти его на второй берег, взять козу , отвезти назад, тут же взять капусту, перевести на второй берег, и вернуться за козой.Так никто никого не съест.

Answer 3

The Problem:

A peasant needs to transport a wolf, a goat, and a cabbage across a river. However, the boat can only hold the peasant and one of the items at a time. If the wolf is left alone with the goat, the wolf will eat the goat. If the goat is left alone with the cabbage, the goat will eat the cabbage. How can the peasant transport all three items across the river without any of them being eaten?

Solution:

To solve this problem, the peasant needs to carefully plan the order in which they transport the items across the river. Here's a step-by-step solution:

1. The peasant takes the goat across the river and leaves it on the other side. 2. The peasant returns alone to the original side of the river. 3. The peasant takes the cabbage across the river and leaves it on the other side. 4. The peasant takes the goat back across the river to the original side. 5. The peasant leaves the goat on the original side and takes the wolf across the river. 6. The peasant leaves the wolf on the other side with the cabbage. 7. The peasant returns alone to the original side. 8. The peasant takes the goat across the river one final time.

By following this sequence of steps, the peasant can successfully transport all three items across the river without any of them being eaten.

Explanation:

The key to solving this problem is to ensure that the wolf and the goat are never left alone together, and the goat and the cabbage are never left alone together. By always having the peasant present on the same side as the wolf, goat, or cabbage, the peasant can prevent any of them from being eaten.

Note: This problem is a classic example of a river crossing puzzle and is often used to test logical reasoning skills.
