This deceptively simple math riddle has gained widespread attention online because it appears easy at first glance, yet consistently leads to disagreement, confusion, and intense debate among people trying to solve it. At its core, the problem presents a situation involving theft, a later purchase, and a cash transaction that includes change being given back to the same individual who originally stole the money.
The narrative begins with a thief entering a retail store and stealing a one hundred dollar bill directly from the cash register. This initial act represents a straightforward loss of cash for the business at that moment. Later in the scenario, the same individual returns to the store and selects seventy dollars worth of merchandise, intending to complete a purchase using the same one hundred dollar bill previously stolen.
The cashier, unaware of the bill’s origin, accepts it as legitimate payment and proceeds to complete the transaction. As part of the sale, the cashier also gives the customer thirty dollars in change. This sequence of events is where most confusion begins, as people attempt to track money flow step by step instead of focusing on net losses to the store.
