Solution explanation for puzzle answer Comment 46 of 46 |
(In reply to answer by K Sengupta)

Assume that Drew is a knight. Then, he has just lied about his own identity. This is a contradiction.

Accordingly, Drew is a liar. Hence, his statement that both Mohammed and himself are liars must be false. Thus, precisely one of them is a liar and the other is a knight.
Since, it has been established  that Drew is a liar, it follows that Mohammed must be the Knight.
