PAY CLOSE ATTENTION;
At the first stop five passengers get on
At the second stop eight passengers get on an three get off.
At the third stop four passengers get on and three get off
You skip the fourth stop.
At the fifth stop four passengers get off and five get on
At the sixth stop twelve passengers get on and five debark.
At the seventh stop two passengers get on and four get off.
Now answer correctly, how old is the bus driver?
Quote: darkozYou'll be surprised how many people get that wrong but I don't know about when its in a written format. Its usually better when asking verbally.
It's much easier written because you can
read it twice. You'll always forget the first line
of the problem because it sounds rhetorical.
What movie :)

This will also explain some system players systems. This is probably what we would get if Bob ever explained any of his BS concerning his RNG spotting technique or Roulette system.Quote: Paigowdan
Quote: AxelWolfAccording to that, I'M, the bus driver. Is that the point? since I know my age, I assume I would get them both correct
Yea, correct. It doesn't work so well written but try it on people verbally. They usually answer wrong.
Here's another one I remember:
A man walks completely along the outer path of a perfectly square park.
The first side takes him an hour and twenty minutes to completely encompass.
The second and third sides also take him the same amount of time.
However, he completes walking along the fourth side in only eighty minutes.
How come?
I'm sure the mathematicians here will get it. And perhaps it doesn't work so well written either. Lets see.
Lots of people get this one wrong, lol.
Entire craps pit missed it one day. SMH
Phydeaux
Mt. Everest (it still existed before it was discovered).
Here's one (it's kinda f*cked up). It's a play on words. "There's a man in a room. There are no doors, windows, nothing, just four walls. There's a wooden table and a mirror in the room with the man. How does the man escape?"
The man looks into the mirror. He sees what he sees and he saw what he saw. He takes the saw and cuts the table in half. He puts both halves back together to make a whole. He jumps out of the hole.
Here's one I got from reddit (I figured it out, surprisingly). It took a few minutes to figure out, though.
"There are 100 prisoners all in solitary confinement. The warden of the prison decides to give them all a test. He will randomly choose prisoners one at a time to go into a room with only a lightbulb. The prisoner can either turn the bulb on if it is off, off it is on, or do nothing and leave it as it was. The goal of the prisoners is eventually have someone say with absolute certainty "All one hundred prisoners have been in this room at least once before." If he is correct, all 100 go free, otherwise all 100 are killed, so whoever says it must be 100% sure that he is correct. The warden gives them one night to plan how to pass the wardens test.
Assumptions: Everyone knows that the lightbulb is off at the beginning. Anyone that goes in only knows whether the lightbulb was on or off when the enter, what they do to the bulb (change it or nothing) and how many times they themselves have been in the room, nothing else. Since everyone is in solitary, no one knows how fast time is passing, and the time in between the warden's choice of prisoner is arbitrary. There is nothing else to know or do in the room besides the status of the lightbulb, and there is no way the prisoners can communicate outside of the one night of planning and the lightbulb.
What is the strategy to beat the warden?"
One prisoner is the "counter". Whenever a prisoner goes into the room for the first time and the light is OFF, he turns it ON. If the light is ON, the prisoner does nothing. If the prisoner has already been in the room, he does nothing. Whenever the "counter" enters the room, if the light is ON he turns it OFF and counts +1. If the light is OFF, he leaves the light OFF and keep the current count. In this way, he will know when the other 99 prisoners have entered the room. When this has happened, he is 100% certain all 100 prisoners have entered the room (counting himself) at least once. Well, that is, assuming the other 99 prisoners are honest and turn the light ON when they are supposed to.
7 times 4 is 28. Had to count on my fingers and did it several times, but am finally quite convinced its 28.Quote: Paigowdan

Very similar structure to "You are driving a school bus. There are 8 stops on the way to the school. At the first stop, you pick up the Shottlehauser kids: Joey, Jeffrey, Julie, and Fred." ....(make up 7 more stops, with names, throw in a couple of twists like "usually there are 3 Huberdubers, but the littlest one, Henry, is sick".) Then you say, "and the question is: What was the bus driver's name?" Almost everybody gets it wrong and thinks they forgot what you told them or didn't listen.

Another variation - I'm not sure if it's from one of the Alice books by Lewis Carroll, or if Raymond Smullyan thought it up for Alice in Puzzleland, but the last question is, "Now, how many people got off at the third stop?" When Alice replies, "Well, I wasn't counting that!", the reply was, "You must count everything, because everything counts!"
