Werewolf Puzzle A certain village has 3 inhabitants, each either human or werewolf. Humans always tell the truth and werewolves always lie. They each make a statement:
Advik says, "At least one of us is a werewolf."
Bardia says, "At least one of us is a human."
Cherry says, "Exactly two of us are werewolves."
What must be true?
The discussion declares Advik as Human like this:
Suppose Advik is a werewolf. Then his claim that there is at least one werewolf would be true, but werewolves can't tell the truth. So he must be a human instead.
It supposes that Advik is a Werewolf but why is it not supposing it a Human?
Secondly Advik doesn't say that he is a werewolf so even if we suppose him a Werewolf, he being the liar does make him a human.
Any help would be highly appreciated.

Each of the three inhabitants is either a human or a werewolf. The given line of reasoning shows that Advik being a werewolf is a contradiction: that would make his statement true but a werewolf cannot utter truth. So Advik, by elimination, must be human; there is therefore no need to assume Advik is a human, we derive it.
