A Knave can't say that statement in this situation as he must always lie. And if he said it, it's impossible to be a lie if you think about it. So A must be a knight and since he always tells the truth B has to be a Knave.

Tim: "I am a joker but Tom is a knave"
Tom: "I am not a joker but Tim is a knight"
Jim: "When Tim and I are in the same room, Tim always lies. But when Tom and I are in the same room, he tells the truth"

Knights tell the truth, knaves lie, jokers just mimic anyone who are in the same room with them
There is only 1 knight, 1 knave and 1 joker
Tim and Tom were in the same room while Jim was outside.

There is only one correct way to arrange twelve people into two rows using the following rules:
Six people A,B,C,D,E and F are sitting in row-1 facing North, and six people P,Q,R,S,T and U are sitting in row-2 facing South, but not necessarily in this order.

Row-2 is above row-1, so every person from one row faces a different person from the other row.

The following information is known about them.

1) B is to the immediate left of C, who does not face Q. Q is third to the left of R.
2) Neither Q nor C sit at the ends. B is to the right of F and D.
3) D faces the person who is third to the right of T, who faces E.
4) P sits second to the left of the person who faces A.
5) S is not an immediate neighbor of P.
