@Johann : You were right this brainteaser is really hard. I don't know where to begin to solve it.
If you don't mind, I'll add another brainteaser to keep the thread going while we all try to figure it out yours (and nordlead's puzzle too!)
So here's mine :
You have 25 horses who all run at a constant speed but not one of them at the same speed. The track only has 5 lanes so you can only race 5 horses at a time. What's the least amount of races that you need to identify the 3 fastest horses.
Signature goes here!
