## “A man steals \$100 from a shop” riddle

“A man steals a \$100 bill from a shop. He then uses that \$100 bill to buy \$70 worth of goods. The shop owner hands him back \$30 in change. How much money did the shop owner lose?”

## What you’re thinking

Seeing all those numbers being bandied about, you might assume this seemingly short riddle requires some lengthier form of calculation. Indeed, the shop owner has lost \$100 right off the bat, but they get that \$100 bill back almost immediately.

Of the \$100 stolen from him, the shopkeeper keeps only \$70, handing back \$30 to the thief. Because this transaction results in the shop owner ending up with \$30 less in the cash register, you might be thinking that the answer is \$30. Or is it the \$70 in merchandise that the shopkeeper will have to replace?

Let’s not forget that when all is said and done, the thief walks away with \$70 worth of goods. So you might be thinking that the shop owner is down the original \$100 plus that \$70 worth of goods, adding up to a total loss of \$170. Or perhaps it’s that the shop owner is down the original \$100 bill plus the \$30 in change he handed over at the end? It could also certainly appear that the shop owner has lost a total of \$200, which is the sum of the original \$100 bill plus the \$70 in merchandise and the \$30 he handed to the thief as change.

Like all the best math riddles, the answer to this one is not what it seems. In fact, when you get right down to it, it might not even qualify as a math riddle. Or it might be the simplest math riddle ever.
