Question

The densities of two solid spheres A and B of the same radii R vary with radial distance r as _A(r)=k ( r R ) and _B(r)=k ( r R )^5, respectively, where k is a constant. The moments of inertia of the individual spheres about axes passing through their centres are I_A and I_B, respectively. If I_B I_A = n 10 , the value of n is
