6 or less liars (Posted on 2015-11-13) Difficulty: 1 of 5
In a small village there are two kinds of people: liars and truthtellers.
Everybody knows everybody and everybody knows as well who is a liar and who’s a truth-teller.
I approach six villagers and pose the same question to each of them:
"How many liars are among you?"

I get six distinct answers (integers, of course) and deduce the true one.

How many liars are in that group?

Liars always lie and truthtellers never do.

Some Thoughts re(2): Summing up - spoiler | Comment 13 of 16 |
(In reply to re: Summing up - spoiler by Dej Mar)

You are absolutely right.

I knew that one can say 6 only if there is a truth teller in the group so

the option  "no 5 but with 6 " (your d.) does not exist.

Somehow when I wrote my "sum up" - forgo to mention it.

Since there is no way to correct the "official" version I am going to edit my comment and post a disclaimer re :   "official answer".

Tnx for your comment.
