Find the true and the false statements.

1. Either 2 and 3 are both false or 2 and 4 are both true.
2. Either 1 is false and 3 is true or 3 is false and 4 is true.
3. If and only if 2 is false, then either 1 or 4 is true.
4. Either 1 and 2 are both false or 3 and 4 are both true.

(In reply to 1 & 4 are true by srilatha)

If 1 & 4 were true (and the others false) then 3 would be false and 4 true, making 2 true also--a contradiction.

Also, please don't place your proposed solution in the subject line of the comment.
