Lies all around (Posted on 2011-06-04)

When Mr. Mathwiz visited the IoK&L* he was surrounded by 20 or 21 male inhabitants, who formed a perfect circle and then each said a single word (either "Knight" or "Liar") about the man on his right.
The wiz then evaluated correctly the exact numbers of liars and the truth-tellers.

What were those numbers?

*IoK&L, is an imaginary island, inhabitated by Liars and by Truth-Tellers a.k.a. Knights.

Solution: (Hide)

20 people- 10 knights and 10 liars, no members of the same kind standing one next to the other.
Why? see Math Man's presentation.
