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?

The answer is the same as Drew and Mohammad. Drew is a liar and Mohammad is a knight.
