Answer 28

im ADHD dyslexic and it's 3 am here and i need to pass his homework by tomorrow or else I won't graduate

Answer 29

ask anyone,

what the other guy will say what you are ?

if you asked a liar, he will answer "truth teller"
if you asked a truth teller, he will answer "liar"

Answer 30

ok, what is not logical about my answer?

Answer 31

same thing...

Answer 32

If I were to ask the other one whether he always tell the truth, what would he say?If no then the one is truth teller, a reply of yes means you're taking to liar

Answer 33

that leads to a paradox @ganeshie8

Answer 34

are you an accurate truth teller

Answer 35

m i right?

Answer 36

no.

Answer 37

i did not say tehre were two people

Answer 38

If he is, he will know that he is (since he is accurate) and truthfully will answer yes. If he is the inaccurate liar, he will believe that he is the accurate truth teller (since he is inaccurate in his beliefs), but then he will lie and say no. So the accurate truth teller will answer yes and the inaccurate liar no to this question.

Answer 39

i said two types

Answer 40

thats right, there must be another answer

Answer 41

liar and truth-teller will respond yes

Answer 42

well that was from a different riddle anyway

Answer 43

Ask the liar if the other person always tells the truth, he will lie and say yes,
Ask the one who always tells the truth if the other always lies, he cannot lie and will say yes.

Answer 44

again...i did not say there are two peopl

Answer 45

Have their SSI, ask them the date they were born, the liar will always give you a false date.

Answer 67

Answer 68

Was it a right hint Igba?

Answer 69

no

Answer 70

"Are you a human being?" qualifies as one of the solutions.
1) It IS JUST ONE QUESTION.
2) You can find out if a person is lying or not.

Answer 71

very far

Answer 72

ok then cant you ask them if they were a liar would they lie to you? cuz then if there a liar and they lie no matter what a liar would respond 'no' no?

Answer 73

ask the 1 person if you are asking the question. a lier will say no, and a trusth teller will say yes

Answer 74

i watched the video// theres millions of question one could come up with that are like that

Answer 75

http://www.youtube.com/watch?v=69rDtSpshAw

Answer 76

like i said before "are you a liar" doesn't work

Answer 77

"Are you a human being" does.

Answer 78

if you would be a liar and i ask you : are you a liar? what do you answer?

Answer 79

"am I asking you a question" will work also

Answer 80

I don't think this is the door riddle, or is it?

Answer 81

@myko it leads to a paradox

Answer 82

"Am I a human being" works too.

Answer 83

well if the liar lie all the time no matter what you could say "2+2=4 right?" 2=2=4 but the liar would say no.

or am i just crazy here? prettyy sure theres millions of answers in that case

Answer 84

i don't see why?

Answer 85

what is wrong with asking " am I asking you a question" ?

Answer 86

liar paradox...heard of it?

Answer 87

no

Answer 88

Hey hey LGB, we answered your question

Answer 89

you talking to me or myko?

Answer 90

that video makes me want to see that movie btw

Answer 91

um, that is the only good part of the movie, unless you like jim henson

Answer 92

if a person says "i am a liar" and he's lying that means he's a truth-teller...but if he's a truth teller and eh says he's a liar that means it's true he's a liar and so it repeats

Answer 93

ok so what about "am I asking you a question"

Answer 94

but i don't ask him if he is a liar, i say: imagin you are a liar.....

Answer 95

a lier will say no and a truth teller will say yes

Answer 96

liar*

Answer 97

again...paradox...how many times do i have to say it
