Riddle: You have twelve pennies. One penny is a phony and has a different mass. You can't tell which penny is the fake.
You have a scale and are allowed three measurements, only.
As the riddle was related to me, I do not know if it is a balance scale or a scale that measures mass.
Can you determine which penny is the fake? If so, how?
