*There is a Truth Teller (always tells the truth), a Liar (always lies), and an Occasional Liar (sometimes lies, and sometimes says the truth). Each of them knows who is who.
You may ask three 'yes or no' questions to determine who is who. Each time you ask a question, it must only be directed to one of them (of your choice). You may ask the same question more than once, but of course it will count towards your total. What are your questions and to whom will you ask them? ?*
In all honesty, I don't know where to start with this type of question. I'm really not looking for an answer, but guidance on how to approach a problem like this.
The condition that
"Each person knows who is who"
Seems to me to be the important part of this, and means I should start with trying to discover the occasional liar, but what I can't work out is the starting question I should ask.
So I then tried to ask each person if they're a liar, which caused me confusion because if I ask 'A' if he is the liar, and he says 'yes', then he is not the liar, as the liar would say 'no'; therefore, he is telling the truth.
But if he says 'no', then he could be telling the truth or a lie and doing this for the other outputs the same result, which confused me even more.
Is there a possibility someone could break this down a little, it would be much appreciated.
Also I am new here and not sure what tags I should tag, so sorry for the wrong input.
