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.

10 cents. One item cost 17 cents (14 cents + 3 cents), the other cost 34 cents (9 cents + 12 cents + 13 cents). Leaving a measly 10 cents left over.

Air: Glad to have a chance to catch my breath. Work has been crazy lately. They split me and my partner and now I got another newbie on the nipple. :-/

The other answer is 13. Make beleive you are buying both items at the same time and dont have to worry about getting the coins to equal to each price. 61-13 leaves 48. 48/3 = 16. one item will cost 16 cent and the other will cost 32 cent. this will leave you with 3 cent and 10 cent coins.

Hammer what happened to Lisa's arm. Hate to she her injured.

Frayed, he payed for both items at the same time. We we looking at it as buying one item with two coins, then buying another otem with three coins and looking for the possibilities. That Turbo is one sharp cookie ;D
