Awww man. It's quiz time. I figured I'd put in a few of these from time to time. You might have heard a few of these, but I'll make sure to throw in some original ones in the future. Here's the first puzzle:
You have 8 coins, one of which is counterfeit. The counterfeit coin has a different weight than the rest of the coins. You are given a balance so you can compare the weight of them. In only two weighings, how do you find the counterfeit coin?
Try not to look at the comments section for the answer. A solution will be posted at Puzzle #1. Goodluck!
