It is hardly surprising that a straightforward math brainteaser has gone viral on the internet in the digital age, where content travels like wildfire. The $100 puzzle has garnered millions of views and generated a lot of discussion among puzzle fans. It asks users to calculate the amount of money a store would have lost if a burglar stole a $100 bill and then made a transaction.
As the brainteaser became popular on the internet, a ton of answers poured into the comments section. Some people boldly declared that the store had lost $100, but others countered that, after deducting the stolen $100 and the thirty cents in change, the true loss was $130.
A few even went so far as to say that the profit margins of the individual transactions determined the store’s overall loss.
