We'll wrap up the old year with a "chestnut" teaser for today's Friday Free-for-all challenge at the mentalfloss.com Brain Game. Good luck:

A lady goes to a hardware store to make a purchase.
"They're only 40 cents each," the salesman tells her,
so the woman replies, "Great, I'll need 250."

The clerk fills her order and informs the customer
"That'll be $1.20, plus tax" before ringing her up.

How is this possible?

Here is the SOLUTION.

THE SOLUTION:

The woman was purchasing address numbers to attach to the front of her house. Her address number is 250, so she needed three numbers, each of which cost 40 cents (plus tax).

Thanks to our wonderful readers for another great year. We'll be back Tuesday!
