How Smart Are You?

Here’s a puzzle that was featured in a Columbo episode we watched last night. Columbo cracked it. Can you? Here it is.

You have three bags full of gold pieces. Two of the bags contain genuine gold pieces weighing one pound each. One contains counterfeit pieces weighing one pound and one ounce each. The only way you can tell them apart is by weighing them.

But all you have is a penny scale and a single penny, so you only get one weighing, no more. Utilizing only your penny and this scale, can you figure out which of the bags contains the counterfeit pieces?

Now the answer to this puzzle is quite simple. “Why didn’t I think of it!” you’ll say, once you know the answer.

Some of you may already know this problem. If you do, don’t spill the beans.

I will reveal the answer after allowing some time for my readers to offer their answers.

And no, I didn’t get it, either! But you and I don’t have the screenwriters on our side.
