Ok, here is one.

You work at a market and you sell flour by the pound from 1 to 40 in whole pounds. All you have is a balance scale and you only want to weigh the flour once per customer. You can purchase weights of any weight from 1 to 40 pounds in whole pounds. The weights are sold on a per weight basis, not by pound. What is the least number of weight(s) you need to purchase (along with their weight(s)) to sell your flour?

Edit: I screwed up. Added the bold text to fix it.

I only worked this for a few minutes, but you can do it with 5 (maybe less?): 27, 13, 5, 3, 1.


Edit: Ya, I'm pretty sure 5 is the smallest number of weights.

That's incorrect.

Hmmm, less than 5...

Answer to the light bulb riddle:

This guy just told me the same riddle, and I couldn't figure it out in 15 mins so he told me the answer :

Turn light switch #1 on, leave it on for 15 minutes or so, then turn it off. Then turn light switch #2 on and immediately go into the room to see if the light is on.

If light is on, #2 is the right one. If light is off, then go up to the bulb and touch it to see if it's hot, if it is, #1 is the right switch. If the light is off and the bulb is not hot, then #3 is the right one.

That was a tricky one.



My turn, it's a pretty popular one:

A father and son goes on a road trip. They didn't get very far when they got into an awful accident, and the father dies. The son is seriously injured and is taken to the emergency room. The surgeon looks at the son, and exclaims, "I can't operate on him! He's my son." How is that possible?

Yep, but most people couldn't get it right (including girls) when they couldn't get a chance to scrutinize the semantics. It's one of my favorites because it also makes a social point.
