A tricky riddle about a store’s financial loss has gone viral, sparking debate online. Originally posted by “Out of Context Human Race,” the puzzle has been viewed millions of times.

The scenario: A man steals $100, then returns to buy $70 worth of goods using the stolen bill, receiving $30 in change. The big question—how much did the store lose?

Breaking it down: The store loses $100 when the money is stolen. But when the thief spends it, the store gets the cash back, meaning the actual loss comes from the $70 in goods and $30 in change, totaling $100.

Some argue the loss is $130, but that mistakenly counts the stolen bill twice. The correct answer? $100—did you get it right?
