Looks like Luke is busy, or something. I sent him this one recently, similar to the send more money problem.

I might have to give you a shrunk score for getting that correct. But I'll let Luke sort that out.

As Luke posts the questions, he never gets any points. So I think we should let him have at least one for this problem as he did solve it first. As copied from PM:
Hi Luke,
On same theme,

CROSS
ROADS+
DANGER

S=3, each letter different, all numbers 1 to 9 used.

Andy




Hey Andy,
heh heh.... here's your answer...

96233
62513
158746

Thanks for that, I just got up now, always nice to wake up to something unexpected, it cheers me up! May I use it in the thread? I'd give the credit to you of course...

Cheers,
Luke.

Hi Guys, I've away for a few days... hopefully I should be able to get 1 post into my time...

Me?! + 1 Point?! No Way... I don't deserve it! ;)

Here's another question:

Q30 (1 point) : The front wheels of a wagon measure 3.5 feet in diameter. The real wheels measure 4.25 feet in diameter. While the wagon is stopped somebody makes a chalk mark on both a front and rear wheel. How far must the wagon travel before both chalks marks return to their initial position at the same time?

Luke.

oops, just saw JDWhale beat me to it, 59.5 * Pi feet. 17 turns of smaller wheel, 14 turns of larger one.
I think you'll find it's a bit more complicated than that ...
