What do you think?
My students obsessed about this problem today.
How would you solve it? You have 100 valuable coins. Well, one of the coins is counterfeit, so it’s not as valuable. It’s either lighter or heavier than the genuine coins. The only tool you have is a balance scale, and you have to pay a fee each time you use it. How will you find the counterfeit coin? |
