I'm sure this is a convoluted way to solve it but it works. As an FYI, I think your example solution is wrong. The average of 218,200,272 is 230 not 233. I assume you wanted the arithmatic mean not geometric

I chose a slightly different layout for the answer, one that to me seemed more streamlined and clear what was being represented.
