Hi!

This question has been posted quite a few times. Here's one discussion:

https://www.beatthegmat.com/gmat-numbers-t10420.html

The "Search Beat the GMAT" function (top right of the page) is very useful and it's always worth putting in a few keywords from your question to see if it's been previously discussed.

Have a great day!
