Distribution of points in a cellular layout

I have a cellular lay out. I have n number of points randomly distributed in this layout. I just want to restrict 0.15*n i.e. 15% of these points in each inner circle. Like there is 60% of n points in the inner cells and 40% of n in outer circle. Here is some input regarding the graph:

R1=1000; % Radius of outer circle
R2=250;   % radius of inner circles
n=100;     % no. of points
C1=[0 0]; % Center of outer circles a
C2=[500  433.012701892219];  center of the inner circles are
C3=[-500 -433.012701892219];
C4=[-500  433.012701892219];
C5=[500  -433.012701892219];

Is it possible to implement?

Is it a very complex question? Do I need to elaborate it more. Wondering why no updates so far?
