Confirming logic behind anwer

Hello! I just want to confirm the logic behind this real quick. I had originally answered 5th or 7th, which is incorrect. Confirming: it can be 5th, 6th, or 7th because J&H being to the right of G confirms 7th is the last possible rank, but not knowing the relationship L or N have to G means that either one of them or both of them could also be to the right of G, making the 5th, 6th and 7th spaces in our 1-9 rank what's possible. Yes? - Want to check and make sure I am thinking about it the right way before clicking on the explanation. Please let me know. :) Thank you!

Hey @pepperlei, thanks for your post. You are exactly right. Based on the rules given, you know for certain that both J and H have to be to the right of G (i.e., that they earn less than G). So, out of the nine individuals identified, G could be the 7th highest paid.

But because you do not know the precise relationship between L, N, and G, G could potentially be paid more than one or both of these folks, too. So G could be the 5th or the 6th highest paid.

Hope this helps! Best of luck.
