- First we suppose that even numbered statements are true and the odd numbered are false.Then statement 70{At least 70 of the statements on this sheet are false.} would be true.,,which implies that this statement(statement 70) would itself be false.Thus this is an incorrect solution.
Now,we suppose that odd numbered statements are true and the even numbered are false.Then statement 69{At least 69 of the statements on this sheet are false.} would be true.,,which implies that the statement 69 would itself be false.Thus this is an incorrect solution.
