Have to throw a few insults in there given that this is the rubber room...this one is pretty tough
You have twenty stacks of ten coins each...
The coins all look, smell, taste the same....
The only difference, is that 19 of the stacks contain 10 coins each that weigh 1 ounce each and 1 stack contains ten coins that each weigh 1.1 ounces...
the question:
you have a digital scale which will shut off after giving you two readings...
so you can only see how much whatever you put on the scale weighs twice...
after your two weighs, you have to identify which of the 20 stacks contains the coins that weigh 1.1 ounce instead of one ounce...
