Turn Tease (Posted on 2012-08-27) Difficulty: 1 of 5
In a remote island, all the inhabitants are either knights, who always speak truthfully or liars, who always speak falsely.

Ten natives of the island are engaged in a conversation. A visitor from a nearby island approaches the natives and, asks them: "How many of you are knights?"

Each of the ten natives answer in turn: 3, 2, 5, 7, 3, 0, 4, 4, 3, 5

In reality, how many of the ten natives are knights?
