I apologize in advance if this post should be in a different area of the forums. I’m taking my deck safety exam tomorrow, so I’m trying to figure this out asap

How do you solve this problem?

You have 590 tons of below deck tonnage. No liquid mud. 84 tons of cargo above deck with a vcg above deck of 2.7 feet, what is the maximum allowed vcg of the remainder of the deck cargo that is permitted? Illustration d036dg

I know how to use the diagram to determine tonnage, but not vcg. Any help is appreciated! Thanks in advance!
