And, in keeping with's an extra credit question (where did the other dollar go?)

3 men go into a hotel. The man behind the desk says a room is $30 so each man pays $10 and goes to the room.

A while later the man behind the desk realized the room was only $25 so he sent the bellboy to the 3 guys' room with $5. On the way the bellboy couldn't figure out how to split $5 evenly between 3 men, so he gave each man a $1 and kept the other $2 for himself.

This meant that the 3 men each paid $9 for the room, which is a total of $27 add the $2 that the bellboy kept = $29. Where is the other dollar?

$25 - room
$3 (3x $1) back to the men
$2 Bellboy

= 30$

The originator of the question worded the riddle irrationally to intentionally confuse.

25 + 5 = 30
30 - 2 = 28

The bellboy gave each man 1$ back, which means he gave them 3$ total back, and kept 2$ = so therefore they paid exactly 27$ for the room. Because 30 - 3 = 27.

It's 27 because the bellboy kept 2, so 25 + 2 = 27.

There is no missing dollar. Everything is accounted for.

You do not add the 2$ the bellboy kept to the 27$ room cost (creating an irrational 29$ cost).
The 27$ room cost includes the 2$ the bellboy kept.
The 27$ cost is AFTER the men got their 3$ back (yet were missing 2$).

Again, in solving FlyingClayDisk's irrational riddle, it was purely a task of working out a basic math problem and quantifying each step of it properly.

The key was to identify that the riddle was presented improperly on purpose, thus designed to confuse the recipient.

After working out the problem, it is clear that there was never a missing dollar at all, but instead that the riddle was irrational.

I do not see that as a very good IQ test, though it is a decent one because it utilizes the most simple form of math and requires me to work the entire situation out while also knowing that 1$ cannot disappear from the 30$ total.

Basically the correct answer is to explain why there is no missing $ and why the riddle is flawed.

Ten cents.

5 minutes.

47 days.

Now to check the answers.

Nope, hold the fort here, not right on the first one....that would make the price wrong. Has to be a nickel.

I got all 3 in just under 30 seconds . . . I consider myself of slightly above average intelligence . . . so not a very good IQ test.

So would the riddle "Why are manhole covers round?" meet your criteria for an acceptable IQ test question?

nine times three is twenty seven, take away the two dollars the bellboy kept and it is twenty five. I actually read it that way, the trick here is the question that is asked and the missing dollar puzzle is not even a real thing. I actually had to think how someone would get this twisted, sort of like what the news does, to make you think something is wrong.

There is no missing dollar. There is a bellboy that is kind of dishonest though, making his own tip. I would bet that if this was real, the bellboy got away with it.

On top of that, twenty five bucks for a room, that has to be a really old problem. Especially a room for three.

I'd sack the bellboy, the thieving little person.
