Here is a riddle that might leave you up the creek without a paddle (pun intended). You might not be an expert rower, but that won’t be a problem as long as you have logic on your side.
Imagine the following situation:
You have 3 animals: 2 sheep and a wolf, and you’re trying to cross a river in a boat that can hold only 2 passengers (you, plus 1 animal). Can you figure out a way to transfer all 3 animals to the other side?
There’s just one catch: the wolf will eat the sheep if left alone with the them, while the wolf won’t harm the sheep as long as you are present. Besides this, you can make as many trips across the river as you want.
Give this problem a try, and when you think you know the answer, scroll down to see how you did.
Bring the wolf with you on your first trip across the river, and leave him on the other side.
Return back across the river, and then bring one sheep across to the other side.
Then, switch the sheep and the wolf, leaving the sheep on the river bank and taking the wolf with you back again.
Then, switch the wolf with the other sheep, leaving the wolf this time and bringing the sheep across the river again.
Now, both sheep are safely across the river, so simply go back for the wolf to transfer the last of the animals to the other side.
