| I have one for you Predis, and for all as well :
You are in front of 9 balls identical in shape, color and size. There is one ball that weights a wee bit more than the others. You have to find which one it is.
You are allowed the use of a scale and 3 weightings only.
Can you find the wee bit heavier ball ?

| Well.
I would say the following;
You put one weight on each side of the scale then add 1 ball to each side. It should be even. Then you change one of the balls and see if there is a difference. If there is no difference you change the ball again. Sooner or later you will find the heavier one. For what it matters, you could do the same exercise without the weights as well.
Predis, OUT !!! | |

Predis, OUT !!! HUMMMMM....maybe I explained the teaser not clearly... You are allowed to use a scale, but can use it only twice. There are no weights involved...only 9 balls, a scale and 3 try outs. Try again Predis | |
