This Saturday I was at a friends house, and her mom told me this insane riddle. At first I was baffled, but it's actually simple. See if you can figure it out!

Quote:
There are three people going to stay at a motel. The cost is $30. The three people decide to split the cost, each paying $10.

Upon arriving at the motel, the bus boy says that the price has been lowered to $25. Since they had already paid, he needed to give them $5.

The three people decided to each take $1 each and give the remaining $2 to the bus boy as a tip. This means they each paid $9 rather than $10 because they were all given $1 back.

If each person paid 9$, then they paid 27$ in total (9*3). Add that to the $2 they gave the bus boy, and you only get 29$.

Where did the last $1 go?
You're going the wrong way. The price is $25, not $30. So you don't add the $2, you subtract and you get $27-$2 = $25.



But yeah, it took me a few minutes to figure it out.
It's expressed incorrectly. If it was expressed correctly, it'd make perfect sense.
They didn't pay 27 for the room and then tip the 2 bucks, the 2 bucks is already included in that 27. Plus 3 dollars back = 30 dollars.
I have seen this before, but I forgot how I figured it out... I was forced to work from scratch.
Yes, its the fact that im adding the 2 to the 25 and then adding the 2 again, rather than the 3 and then the 2.


Hooray!

Its a trick qn.
Old.

This guy goes to a zoo and visits the Llama enclosure. There's this great big sign that says: "Beware, the llama spits." And he was.

Go for it.
The "guy" who went to the zoo was a llama?
He was ware?
