Logic Problem

[69Shooter]

I heard this many years ago but was reminded of it this morning...

You are trapped in a room that has two doors. One door leads out of the room and the other door goes nowhere. There are two other people in the room with you. One of these pepople always lies and the other always tells the truth. Each of them knows which is which but, of course, you do not. In addition, each of these two people know which door leads out of the room. You are allowed to ask one question to either of these two, the answer to which must lead you to the door that will allow you to leave the room. The question cannot be a multi-part question. What is the question?

if I were to ask the other one which door leads to freedom, what would she say?

if I were to ask the other one which door leads to freedom, what would she say?

And the answer to the question would be?

 

[The Fruity Hare]

And the answer to the question would be?

Use the logic.

Say the good door is A.

If he asks the liar if the truthful one will say door A or door B, the liar will say the truthful person will say door B.

If he asks the truthful one what the liar will say, he will say door B.

So he knows, either way, the correct answer is door A.

 

[papasmerf]

And the answer to the question would be?

The wrong door

 

[69Shooter]

Or, in a more general sense the answer will always be the door that does not lead to freedom, thus, you always take the opposite door.

Math is my friend

I always liked this problem because most people have trouble understanding the answer once they've been told what the answer is. Plus there's no bullshit answer like... "he lived in a lighthouse." or "henry was a goldfish." or "52 bicycles referred to a deck of bicycle playing cards."... which aren't really logic problems but games.

people confuse math for numbers. In reality it is an exercise in logic

Huh?

Two planes take off at the same exact moment. They are flying across the Atlantic. One leaves New York and is flying to Paris at 500 miles per hour. The other leaves Paris and is flying to New York at only 450 miles per hour ( because of a strong head wind ).

Which one will be closer to Paris when they meet?

neither if you presented all the facts.

You see you never gave us a course or destination of either plane.

One could be going to Greenland from Paris and the other to the Antarctic.

 

[spacyfoil]

Papa,

You're partly correct, answer is neither. But not because I didn't give you a course or destination.

But the point is they MEET. Doesn't matter where, cause at the time they meet, they are equal distance from Paris.

You assume one is headed to Paris and the other to NY.

You also assume reciprocal flight paths whis would prove to be fatal.

You should work for the government.

LOL. What does New York and Berlin have in common.




They are the same distance from each other.

They are the same distance from each other.

When Berlin changes their clocks and falls backwards while you are in flight, does it take less time to get there from New York??

Close, but they should be on different flight levels (i.e. still separated by 1000 feet of elevation when they "meet").

 

[Don Draper]

You are allowed to ask one question to either of these two,

Allowed by whom?
