First find two that weigh the same by going through them and balancing them against each other (they're not gonna be hard to find 8 out of ten!). Then pick one and weigh the other seven against it until you find one that tips it.

Trivial. If you have a set of three marbles, you can easily find out which is the heavy one : Take out one marble, and balance the other two. If the two are equal in weight, you know that the one you took out is heavier; otherwise you know which is heavier.
So then, apply this strategy to a larger scale : Take out three marbles from the set. Divide the remaining six into two sets of three, and balance those two. If one of those is heavier, you know which set of three contains the heavy marble, and proceed as above. If they are equal in weight, then the three you took out contain the heavier marble, and again proceed as before.

Dagonee: Does it have anything to do with how the letters are laid out on the standard keyboard and which fingers are used to type them?

That threw me off at first, but I looked at everything else and it worked, so I figured it was a mistake or typo...

I laid out the letters according to the font in the reply form, in which B has no horizontal line of symmetry.
See:
code:
B
Edit: The B in the main font doesn't have horizonatal symmetry, either. The top loop is shorter than the bottom by one pixel.

you have a double balence scale scale and you need weights for it unfortunatly you only have enough money for 4 weights. what size weights should you buy to weigh things from 1-40 all inclusive (unit doesn't matter)
