okay *streatches fingers, cracking knuckles*

*clears damn throat*

(I don't know the answer to this, and it's giving me insonmia)

three people eat at a restaurant. the meal costs them 30 dollars total. each of them pays $10. The waiter takes their bill, but upon further observation, the manager realizes that there was a mistake, and it only costs a total of 25 dollars, and gives the waiter 5 dollars to give back to the customers. The waiter, being a sneaky fellow, pockets 2 dollars. He gives the remaining 3 dollars to the customers.

Now here's the tricky part.

They each get one dollar back, so the total they each pay is $9, right? 9 multiplied by 3=27.

add the waiter's pocketed $2, and you have $29.

where did the $1 go?

As for the topic: It's not really a riddle since there's no answer. It's just a mathematic anomaly.

the 2 dollars is counted twice.

once in the $27 and then the riddle adds it on again to get 29. when in fact it should add the 3 dollars that were given back to the guys.

They do the sum wrong.

They say it wrong so it misleads you.

Well you gotta remember that the manager only has $25, not 30.

9x3= 27

27 - 2 = 25.

More to the point, where can you get a 10 dollar meal these days?

Edit:

Manager has $25 in pocket
Customers have $3 in pocket
Waiter has $2 in pocket

= $30

$9 each
9 x 3 = 27 correct? yes
you dont add the $2 to 27 you subtract it.

$25 meal, $3 returned to the customers, $2 pocketed by waitertheif.

The answer is simple.

$25 + 5 = 30 - (the 2$ pocketed by the Waiter) = 28

Therefore your dividing by 28. Each person paid. 9.333333333

It may not technically be a paradox, but it's considered a paradox.

It's not a paradox and most definetely not a riddle.

It is simply that the way the problem is described, it's mathematically incorrect.

$10 + $10 + $10 -> $1 + $1 + $1 + $25 + $2

(10-1) + (10-1) + (10-1) -> 0+0+0 + 25 + 2
9+9+9 -2 ->25

The dollar didn't go anywhere.

It's simply misleading the way it's worded.

If You look at the above separation, you see that if you keep the equation/balance of money correctly, you actually have to subtract 2 to get the meal money, adding 2 would be mathematically incorrect, so that's why you get 29. It's because you ADD 2, which detracts from the scope of the question.

There is no extra dollar.
30 - 25 = 5

5 - 2 = 3, they each get one dollar back + the $2 the waiter pocketed, ergo 30.

The last sentence is a throw-off.

They paid 27, the two that the waiter has pocketed is included in that.
27 - 2 = 25, which covers the bill.
