You have ten stacks of identical looking gold coins.
Nine of the stacks contain all real gold coins, and one of the stacks is made up entirely of fake gold coins. Each real gold coin weighs exactly 1 gram, while each fake gold coin weighs exactly 1.1 grams. Using a scale, how can you determine the stack of fake coins?
RULES: You can use to take only one measurement. For example, you stack what you want on the scale, press a button, and get a readout of the weight. You can do this only once, and once the readout is displayed it does not change if you remove any coins. You can mix the coins up in their stacks, separate them, mark them, whatever. How do you find out for sure which stack contains the fake gold coins? :evil:

First You label the Stacks (label all the coins in stack One 1, Stack Two 2. etc..). Then you take 1 coin from stack One, 2 coins from stack Two, 3 coins from stack Three, 4 Coins from stack Four, 5 coins from stack Five...and so on and so on. Then you put the coins that u took onto the scale. Now if there were no fake coins the scale should equal 55 grams. If it was 55.1 then the fake coins are in stack One, 55.2 stack Two, 55.3 stack Three, 55.4 in stack Four, etc... :)

On the scale, place one coin from the first stack, two from the second stack, three from the third stack, and so on up to ten. Press the button to get the readout of the total weight. The number in the decimal place of the scale readout tells you how many of the fake coins are on the scale, and also which of your stacks contained the fake coins.
