- Hi there!I just joined your newsgroup a few days ago and I had fun to solve the
- parachutist and the handshake enigmas.I've got some, I just hope that they were
- never asked before.So, here's the first one:
-
- You have 10 vending machines to fill out with chocolate bars. In fact, after finishing
- to put the chocolate, you remember that you had 9 boxes of chocolate bars of 100g. and
- one box of bars of 90g and you gotta know in which machine you put those of 90g. You
- cannot tell just by looking on the paper on the bar if it has 90 or 100 g. But, beside the 10
- vending machine, you have an electronic weighing machine. When you put a quarter in it
- , it tells you the weight (it makes only one measure). The problem is that you have only a
- quarter (only one try) and you gotta know , just by one try, in which machine you put
- the chocolate bars of 90g. You don't have access to the money of the vending machines.
- You can weigh as much bars as you want, but you can take one measure.
-
- How can you do this (it's mathematic)?
