Lies all around (Posted on 2011-06-04) Difficulty: 3 of 5
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.

what if...? :-) | Comment 7 of 10 |
i'm just thinking...
If there were 21 inhabitants and all said liar except one said knight or all said knight and one said liar is there more than one answer for this ? 'cause i cant find except one ( 11 liars / 10 knights & 20 liars / 1 knight respectively ) 

i hope anyone would reply by posting the other possible answers :-)

thanks in advance.
