       Get out your paper & pencil because I have a new puzzle for you!!


PUZZLE #35  Which coins are where?        Sept. 24-28

 

       Suppose you are shown 3 small cans with individual labels of 10cents, 15cents, and 20cents.

       You are told each can contains 2 coins, one has 2 nickels, one has a dime and a nickel, and one has 2 dimes. But you cannot see in the cans.

       You are also told that each can is mislabeled.

       If you are allowed to look in only one can, how can you determine exactly which coins are in which can?
