| | | | Weighing Thanks Jack for this riddleWe have 12 billard balls (numbered from 1 to 12) and a pair of scales.
One of these balls is havier than the other balls. How can we find this ball with maximum 3 weighings? Congratulations Le Pougnezu on his solution of the 04/07/06 but don't look at it, it's always better to find oneself...
