Glam--you only weigh two of the final three. If one of the two is lighter, then Bob's your uncle. If they are the same, the one you left out is the light one.

sj, thanks, I believe that is just right. There's a reason I was an English major!
Yeah, I'm lucky to be able to understand the answer. UGH things like this make me feel so fucking stupid.
Logic puzzles like that just stress me out and make me feel dumb. I know they're supposed to demonstrate problem solving skills, but I hate them.
Timelies all!

Exactly. And I feel like I have pretty good skills at actually solving problems. Except when presented with a logic puzzle which makes me feel like I'm defective and lucky to have gotten anywhere in life.
Start with three piles of three and weigh two of them. One will be lighter, or the one that is not weighed will be lighter. Repeat with the three pennies in the lighter stack.
But 3 piles of 3 is nine pennies. The question was about 8 pennies. That technique won't work with 8.

I was just coming here to post that! I was driving myself nuts trying to figure out how only 2 measurements would work with 8 pennies.

Thanks for pointing that out!! I didn't trust that I was actually correct about that.

It me! I remember thinking I was awful at math until I started doing real life math at my job with an investment management co. I can actually do that shit when the numbers have life stuff attached to them!
