Is this correct - confused in this riddle - where does the one rupee come from....? I have 50 rupees, and spending like this and where does that ONE rupee come from.... am right or wrong ?????? !WHERE DOES THE ONE RUPEE COME FROM

The sum of the balance column is meaningless. If you spend 1 rupee at a time, your balance column total will be 49+48+47+...+1=1225. What does that number mean? Nothing whatsoever.
