This phrase is where I'd start :

        "Mr. Salesman's wife is the teacher's twin sister."

So, the teacher is the twin brother of Mr. Salesman's wife. Or in other words ... Mr. Salesman cannot be the teacher (or he'd be married to his own twin sister).
So the only ones left that can be the teacher are either Mr. Newsman or Mr. Teach. But then :

        "NONE of them has a job which is the same as his name. "

Which eliminates one of the two, and we end up knowing who the teacher is.

Once we know that, we can easily figure out who the salesman is by again applying the rule :

        "NONE of them has a job which is the same as his name. "

I'll leave that to you ;)
