Last week’s puzzle asked, “What day comes three days after the day which comes two days after the day which comes immediately after the day which comes two days after Monday?” The answer? Tuesday! Congrats to Jasmine K, who sent in the correct answer. This week, we’ll have a special treat: two brainteasers! (Remember, don’t post the answer in the comments. Let everybody have a chance to figure it out!)
First, see if you can solve this classic river crossing problem. A farmer bought a fox, a chicken, and a cabbage at a market. On the way back home, he has to cross a river. His small boat will hold, besides himself, just one item. If he leaves the wolf and the goat together, the wolf will eat the goat. If he leaves the goat and the cabbage together, the goat will eat the cabbage. How does he get everything across the river?
Now, if you already knew that puzzle, or if you found it too simple, here’s a more challenging take on it! This time, the farmer has to take a fox, a chicken, a caterpillar, and the cabbage across a river in his little boat. He’s gotten a slightly bigger boat, which can hold 2 two items aside from himself. The fox would eat the chicken if they are left unattended. The chicken would eat the caterpillar if left unattended. The caterpillar would eat the lettuce if unattended. How can he take everything across?
