Six Coins
Puzzle for all you math guys out there.
Six Coins...
You have six coins with the following values (you live in a remote country, of course): 3 cents, 9 cents, 10 cents, 12 cents, 13 cents, and 14 cents. You use five of them to buy two articles. One costs twice as many cents as the other. What is the value of the coin you kept?
Let me know when you give up. Hint there are two possible solutions.
