Question-
Simon was at a carnival and went to a booth where Johnny said to the Simon, "If I write your exact weight on this piece of paper then you have to give me 50 dollars, but if I cannot, I will pay you 50 dollars."
Simon looked around and saw no
scale so he agrees, thinking no matter what the Johnny writes he'll just say he weighs more or less.
In the end the Simon ended up paying the Johnny 50 dollars.
How did the Johnny win the bet?
