If two people are of the same type,then they are either both knights or both liars. If they are of different types,then one is a knight and one is a liar. Now, suppose Drew and Mohammad say the following.

Drew: We are of the same type.
Mohammad: We are of different types.

Now, what are each?

If they are the same type, then they would give the same reponse. So they are of different types.

In that case, Mohammed, who makes a true statement is a Knight, and Drew, who makes a false statement, is a Liar.
