I always seem to make some silly mistakes on Number Properties problems. So I created this chart containing the "Big 7" numbers, the number properties, IMHO, that one must check before proceeding to select an answer. Below is a screenshot of the notes that I made to remind myself of these rules (correct me if I screwed up on something), hope it helps you guys as well:
As pointed our by jakelong1, I've added an attachment that adds a perspective to the above image, which hopefully should clear up any confusion:

Bro.. can you please explain this diagram first, because without any info I was able to deduce most, but not great in confidence so wanted to cross check whether I was right or not. It would be great if you could explain what exactly you are trying to do here

Thanks for pointing out. I use it as my memory aid, and you are probably right that it wont make any sense without some information on how I came to this level of abstraction. I basically got this from "Chilli Hot GMAT", it's a great refresher, and also has a lot of practice problems. You can purchase it at Amazon, it also comes in Kindle format -- which is what I purchased. Anyway, here's the excerpt from the book that further explains the Big-7 numbers (I basically abstracted my memory aid above from the reasoning mentioned below):
