Riddle 1 A farmer returns from the market, where he bought a goat, a cabbage and a wolf (what a crazy market). On the way home he must cross a river. His boat is small and won’t fit morethan one of his purchases. He cannot leave the goat alone with the cabbage (because the goat would eat it), nor he can leave the goat alone with the wolf (because the goat would be eaten). How can the farmer get everything on the other side in this river crossing puzzle? Riddle 2 Three humans, one big monkey, and two small monkeys are to cross a river: (a) Only humans and the big monkey can row the boat. (b) At all times, the number of humans on either side of the river must be greater or equal to the number of monkeys on that side (or else the humans will be killed by the monkeys!). (c) The boat only has room for two (monkeys or humans). (d) Monkeys can jump out of the boat when it’s on the river bank. How will they cross the river? Help them out.
Answers
Explanation:
1. He should first take the goat to the other side as the wolf will not eat the cabbage. Next, he should take the cabbage, leave it on the other side and take the goat along. Leave the goat on the original side and take the wolf to the other side and leave it. Finally, come back and take the boat to the other side.
