Questions

1) There's 10 bag of marbles. 9 of these bag has 10 marbles that weigh 1g each and another bag of 10 marbles that weigh 0.1g each. You have one weighing machine that can only be used once. How can you tell which bag contains the one with 10 0.1g marbles assuming the marbles look identical and you can't feel the weight with your hands.
Hint: you can remove the marbles from the bag.

2) You have a bar of chocolate that has 7 collums. You employ a worker for a week with the pay of 1 collum per day. You can only cut the bar 2 times. In what way can you cut to ensure that the worker has the correct number of collum he earn after a days work. (1st day he has 1 collum, 2nd day 2 and so on.)

For the answer, ask. =)
