Suppose you have a sample of G$-$type stars in three regions: A $(85-95$ pc$),$ B $(95-105$ pc$)$ and C $(105-115$ pc$).$ If the density is uniform and there are $10$ such stars in region B$,$ how many are in regions A and B$?$ Round to the nearest integer, and for simplicity, let all stars in region A be at $90$ pc$,$ those in B at $100$ pc$,$ and those in region C at $110$ pc
