Answer:

  • Sue is knave and Marge be knight

Step-by-step explanation:

Let Sue be knight and Marge be knave.

Sue says: "Marge is a knave". Since Sue is knight, she is right and Marge should lie.

Marge says: "Sue and I are not the same." - this is right answer too, so  this is not a correct response and our assumption is wrong.

Now, let Sue be knave and Marge be knight. Then Marge's response is right and Sue's is wrong. This is a match and this assumption is correct.
