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 two statements disagree with each other, so they cannot both be of the same type, meaning Mohammad is still the knight and Drew is still the liar.
