Some riddles look incredibly simple at first, yet they continue to confuse people long after they hear them. One classic example is a short math puzzle involving a store, a stolen bill, and a purchase. Even though the numbers are small, people often arrive at completely different answers.
The reason is simple: the wording tricks many readers into counting the same money more than once.
The Riddle
A man steals a $100 bill from a store register.
Later, he returns to the same store and uses that same $100 bill to buy $70 worth of merchandise. The cashier gives him $30 in change.
So the question is:
How much money did the store actually lose?
Why People Get Different Answers
Many people quickly respond with answers like:
$200
$170
$130
At first, those numbers may seem reasonable because the situation feels complicated. Some people count the stolen money separately from the merchandise and change. Others try to add every transaction together step by step.
But the key detail is that the original $100 bill eventually returns to the cash register during the purchase.
That means the store ends up with the same $100 bill back in the drawer.
The Correct Answer
What the store permanently loses is:
$70 worth of merchandise
$30 in cash given as change
When added together:
$70 + $30 = $100
So the store’s total loss is exactly $100.
A Simpler Way to Understand It
Imagine the thief walked into the store and simply took:
$70 worth of products
$30 in cash
In that case, the total loss would clearly be $100.
The confusion only happens because people accidentally count the same $100 bill twice — once when it is stolen and again when it is used during the purchase.
Why These Riddles Are So Popular
Puzzles like this are entertaining because they test logical thinking more than difficult math skills. The wording encourages readers to overthink a situation that is actually straightforward once broken down carefully.
That is why this riddle continues to spark debates online, even though the final answer stays the same every time.
✅ The store lost exactly $100.
