Answer 2

Answer:

According to the question the person approached me should be a Joker.

Explanation:

The person approached should be a joker because Knights always tell truth.

As the person told he was Knave there is no such possibility.

Knave always tell lie so he cannot present himself as Knave.

So only possibility is the person should be a Joker.
