Here is the information :
You have 10 bags with 10 in every bag. Each ball has a weight of 10 gramm. Only in 1 bag the balls weights are 9 gramm each.
Here is the question : You can do whatever you want ,for example put the balls from one bag in the other. You only have the chance to weigh them 1 time . After this you have to tell in wich bag the balls with 9 gramms are.
I will post the answer later ^^
You are in a cabin and it is pitch black. You have one match on you. Which do you light first, the newspaper, the lamp, the candle, or the fire?
i know the answer but i will let the others have their fun too ^^
