| Cannibals and Missionaries | Situation: There are three cannibals and three missionaries
on one side of the river. There is only one canoe which will hold at most
two people at a time. When the canoe is taken across the river, at least
one preson must bring it back in order for the others to cross.
Object: You must get all the cannibals and all the missionaries across
the river, but at no time can the cannibals outnumber the missionaries
on either side of the river. It is okay for the missionaries to out
number the canniblas at any time. |

| Children | A man walks into a bar, orders a drink, and starts
chatting with the bartender. After a while, he learns that the bartender
has three children. "How old are your children?" he asks. "Well,"
replies the bartender, "the product of their ages is 72." The
man thinks for a moment and then says, "that's not enough information."
"All right," continues the bartender, "if you go outside
and look at the building number posted over the door to the bar, you'll
see the sum of the ages." The man steps outside, and after a few
moments he reenters and declares, "Still not enough!" The bartender
smiles and says, "My youngest just loves strawberry ice cream."
How old are the children? A variant of the problem is for the sum of the
ages to be 13 and the product of the ages to be the number posted over
the door. In this case, it is the oldest that loves ice cream. Then how
old are they? |
