There was once three fortune tellers, namely Truth (who always tell the truth), Lie (who always lies), and Wise (who sometimes tells the truth or lies). An investigator was sent to know if who is the Truth, Lie, and Wise.
The investigator asks the one who is sitting on the left: "Who is sitting next to you?" She replied: "Truth".
The investigator asks the one who is sitting on the middle: "Who are you?" She replied: "Wise".
The investigator asks the one who is sitting on the right: "Who is sitting next to you?" She replied: "Lie."
Who is sitting on the left, middle, and right respectively?

Let's analyze each sentence.
The first lady (on the left) can't be Truth because she never lies. She would certainly not have said her own name.
The second lady (at the middle) also can't be Truth . If she were, she would have said her own name.
The above two statements imply that the last lady (at the right) is Truth . Her statement would imply that the middle lady is Lie & that implies that the first lady would be Wise .
