Alright kids, get out your pencils and make a cup of coffee, because this one will keep you up at night.
Using the digits 1 through 9, with no repeats, find two numbers, where the larger one is exactly double the smaller one.
Thank my Dad for this one - he gave it to me last night, and I got the right answer at quarter to midnight. I know there is one solution, but is it unique? There may be more than one correct answer!
The first commenter with the correct answer will recieve the grand prize, which is the satisfaction of being the first one right, along with the dubious honor of being called a Math Geek like me. (And for those of you who don't want to play, I'll post my answer in the comments section later.) Ready? Set? GO!
