Question

Toggler riddle.

You have 5 people in front of you. 4 of them are togglers. A toggler is a person who alternatively speaks the truth and the untruth. For example if I am a toggler and you ask me my name, I may speak the truth for the first time, but then I'll lie, then I'll speak the truth, then I'll lie. For example I will say:
I am Parth. If you ask again
I am lgba. Ask again:
I am Parth

Now there is one truthteller who always tells the truth.

You have to ask two questions to any two people(you may ask the same person) and you have to know the truthteller. How will you know?

Answer 1

Notice that the toggler may also lie on their first chance.

Answer 2

can they tell the truth first time and second time?

Answer 3

Only the truthteller can speak the truth all the time. The togglers would speak truths and lies alternatively.

Answer 4

I suspect you have to ask something about what they'll say when the question is asked again.

Answer 5

Hmm no

Answer 6

Will you be able to know who the truthteller is?

Answer 7

Not something like, "If I ask this question to this guy, will he tell the truth?" ??

Answer 8

No actually. That's some other riddle. This is the harder version.

Answer 9

then ask the name twice

Answer 10

No, you wouldn't be able to know then.

Answer 11

the one who doesnt change answers is the truthteller

Answer 12

Only two questions.

Answer 13

Am I correct in saying that you have to ask the same questions to only one person?

Answer 14

Yes! But what will you ask?

Answer 15

And another thing....we don't have the same question for everybody. You'll have to think for each of those.

Answer 16

Ask he same person twice

Answer 17

Yeah but what do you ask?

Answer 18

If its a toggler then he will change answers and yo uwill know he is the togler

Answer 19

You have to see who is the truthteller btw

Answer 20

If its the truth teller he will say the same thing twice

Answer 21

Or

Answer 22

Ask them each who is the truth teller and if they say the something then that person is the truthteller

Answer 23

Ok think that there are 5 guys and then choose a guy you wanna talk to.

Answer 24

If they say something different you are in some trouble

Answer 25

ask them "who farted"

Answer 26

XD

Answer 27

Choose the guy you wanna talk to

Answer 28

The problem is that there are so many possibilities; the idea is to reduce those possibilities into a few using a specific question.
I have a few ideas in mind, such as "Is one of you a truth-teller?", but I can't find a question where I have information, whether or not they lied.

Answer 29

Ok you want the solution?

Answer 30

Answer 31

Answer 32

Answer 33

Answer 34

wait

Answer 35

I think i got it

Answer 36

Google is great. Wow

Answer 37

First ask one Are you the truth teller?

Answer 38

If the person responds "Yes". They are either the truth teller or they are a toggler that has just lied to you that will now tell you the truth. Either way the next answer will be truthful. Therefore ask who is the truth teller.

Answer 39

f the answer to question 1 is "no". They have to be a toggler that has just told you the truth. Therefore the next question will be a lie. Therefore the question " who is a toggler" will reveal the truth teller.

Answer 45

Do you want the solution guys?

Answer 46

Ask - Are you the truthteller?
YES - either a lying toggler or a truthteller will say this.
You ask next - who is the truthteller?
The truthteller will say 'me'
The lying toggler will speak the truth

Answer 47

Actually you'll ask are you a toggler? if he says yes then he is a truthtelling toggler and the next time you'll ask who is not the truthteller

Answer 48

If he says no then it's a lying toggler or a truthteller
