The name trade

Logic Level 2

Carson Palmer and Watson Brown each have two last names,

Larry Ned and Mike Scott each have two first names.

They agree to a trade where each of them will end up with one first name and one last name.

After the trade, Ned Brown immediately left to have his car repaired. The other three men chatted for a bit.

Larry made a joke that Mr. Watson laughed at.

Scott and Mr. Carson discussed what dance clubs had the hottest women.

Mike suggested to Mr. Palmer that he should claim he's related to Arnold.

Larry told Mike that if Scott had done things differently, Scott's new initials would have formed one of the eight standard compass points.

What is Larry's new last name?

Carson Watson Palmer

Larry is not Mr. Watson.

Scott is not Mr. Carson

Mike is not Mr. Palmer.

And Scott's initials are not "SW", so Scott is not Mr. Watson. Therefore, Scott is Mr. Palmer.

Thus, Larry is not Mr. Palmer. He's also not Mr. Watson, so he must be Mr. Carson.

The complete set: Ned Brown, Larry Carson, Scott Palmer, Mike Watson.

I do not understand what you mean by "Carson Palmer has two last names".

I am guessing that it would be much clearer to say "4 friends have first name of A, B, C, D, and last names of W, X, Y, Z." and then start with "Ned Brown left to have his car repaired". I think this is what you intended. If not, please help clarify the initial scenario.

No, I meant exactly what I said. Four men started out with the names of Carson Palmer, Watson Brown, Larry Ned and Mike Scott and agreed to swap around their names so that each one would have one first name (Scott, Mike, Ned, Larry) and one last name (Brown, Carson, Watson, Palmer).

Right, so it's much better to make it obivous that "swap around their names so that each one would have one first name (Scott, Mike, Ned, Larry) and one last name (Brown, Carson, Watson, Palmer)."

Currently, I am wondering "What does it mean that Carson Palmer has two last names"? Is it that he could also be known as Carson Young?

@Calvin Lin It means that he has two names that are normally used as last names.

Did you ever read Encyclopedia Brown as a kid? There's one where Bugs Meany encounters a boy carrying a yo-yo. Bugs steals the yo-yo and then asks the boy his name.

The boy replies, "Elmo Thomas."

"Go buy yourself a last name," Bugs replies, flipping Elmo a penny.

@Denton Young Nope, not read Brown. And I'm not American either, so this "first name" / "last name" business always confuses me. It is not obvious (to me) that "he has two names that are normally used as last names". I would encourage you to clarify that at the start of the problem.

But otherwise, it is a nice problem.
