Fun logic problem 3: dating an ax murderer

Question

Sparks: if you ask, "are you good in bed"?

truth: yes

liar: no

ax: yes ;)

Answer 1

HINT NUMBER 2

Have s*x with all three then leave. Hopefully you gave them a fake name and number

Answer 2

Haha, ask the girl who tells the truth which girl is the ax murderer. Easy as pie.

Answer 3

I think I'd just ask, do you want to have s*x?  

Answer 4

I would ask one, are you the liar, if she says yes then she must be the axe murderer because only an axe murderer would cliam to be the liar.  

Any other response and your not sure.

(edit)

OK - I got it.  You ask girl No. 1 if either of the other girls always calls girl No. 2 an axe murderer.  If she's the liar and she sais yes, then girl 3 is the axe murderer.  If she's truthful and says yes then girl 3 is the axe murderer.  If she's the liar and she says no, then girl 2 is the axe murderer.  If she's truthful and she says no then girl 2 is the axe murderer.  You can eliminate one girl and don't date the one you asked.

If she says yes then date girl 2, otherwise date girl 3.

(edit)

Opps - nearly got axed then.  I've got it now though.



Ask girl 1, if I were to ask another girl, not the ax if girl 2 is ax would she say yes?

girl 1 lie, girl 2 true girl 3 ax   answer = yes

girl 1 lie girl 2 ax girl 3 true  answer = no

girl 1 true girl 2 lie girl 3 ax answer = yes

girl 1 true girl 2 ax girl 3 lie answer = no

answer no then date girl 3

answer yes then date girl 2

Once you had eliminated one potential axe murderer, if by chance you were allowed another question, you could find out who the axe murderer is and try for a threesome even though you still wouldn't know who was telling you the truth.

Answer 5

Is the 'fun' part you watching us hurting our brains thinking and then telling us that there is no solution?

Answer 6

It's a difficult one.  But this might work.

Ask them are they good in bed.

The girl that tells the truth will say 'yes'.

The girl that lies will say 'no'.

The ax murderer will say (hopefully) 'sometimes'.

Answer 7

ask the one who tells the truth if the random answering one is the ax murder.

Answer 8

it's impossible. if you ask the girl that tells the truth se could answer "well ti's not that girl" and then you still are left with two girls. if you ask the liar she could say "well it's me" or she could say "its that girl" that puts you back in the same situation as the first girl. and then theres the random one who doesn't matter what she says its random so. and there is no way of cross checking. however you could look to see who carries an ax with them and if it's bloody or not. check their house for one ect ect do stuff like that w/o asking them

Answer 9

Frivolous answer:

You say "They're having a "Buy 1 Get 1 Free" sale on axes at WalMart",

and see who takes off.

Serious answer:

Identify the girls as A, B, and C.

Ask girl "A" this question:

"If I ask the girl who is not you and not the axe murderer,

'Is B the axe murderer ?', what would the answer be ?"

Both the liar and truth teller will give an inverted answer to this.

So when the answer is "no", you pick C,

and when the answer is "yes" you pick B.

If A happens to be the axe murderer, the answer could be

either way, but you don't care, because you are not dating

her in any case.

Thanks for the helpful hint!

Answer 10

Ok this is my key - Girl 1 = Truth

Girl 2 = Lie

Girl 3 = Axe Murderer

Alright I think I got it. You go up to one of the 3 girls (since you have no idea which is which) and you ask her "If you were the girl who always lies, which girl would you say is not the axe murderer". If it is Girl1 she will tell you the truth and say Girl3, because since she was put in the position of the girl that lies, she has to tell the truth about what Girl2 would say.

If you ask Girl2(liar) the same question, she will lie and say what she wouldn't say, which means she would expose Girl3 as the axe murderer. The logic behind this is that she ALWAYS lies so she lies about what she herself would say (I know i just repeated myself).

And finnily if you ask Girl3(AxeHappy) the SAME question ("If you were the girl who always lies, who would you say is NOT the axe murderer") It doesn't matter if she tells the truth OR if she lies. Let me explain: If she decided to tell the truth, she will truthfully say that it is neither Girl1 or Girl2 which exposes herself as the murderer. On the other hand, if she decided to lie she will lie about what the liar will say (basicly she will say that she is the axe murderer).

IN CONCLUSION the correct question is "If you were the girl who always lies, who would you say is not the axe murderer."

:) Did I get it?

OH and I forgot to add, the one you choose is the girl that isnt mentioned at all. Basicly, if you asked girl1 the question, you pick neither her or the girl she said was not the axe murderer(who she said was girl3, if you remember).. (remember the question). And if you asked girl2, you pick neither girl2 or girl3 (since she said the answer was girl3). And if you picked girl3 to ask, you dont pick her or girl1/2(depending on which one she answered.. you pick the one she did not answer).

Breaking it down further: If you asked the following:

Girl1 - Answered Girl3 so you avoid her and Girl3, thus picking Girl2 to date

Girl2 - Answered Girl3, so you avoid her and Girl3, thus picking Girl2 to date

Girl3 - Answered EITHER Girl1 OR Girl2 (the answer would be random), so you avoid Girl3 (which matters most) and Girl1 Or Girl2 (again, depending on what she answered), thus you pick Girl1 or Girl2

No bro you are not asking if you asked the liar, you are asking if she was the liar how would she answer. Like if I went up to the girl and said "If YOU were the liar, who would YOU say is the axe murderer".. if you read all of that breaking down it makes sense.
