four particles each of mass M is lying symmetrically on the disc of mass 6M and radiusR. moment of inertia of this system about an axis passing through one of the particle and perpendicular to the plane of the disc?

You did not attach a diagram and so it was difficult to imagine where the particles of masses m were exactly placed even though symmetrically but there are a number of ways you could place them symmetrically I assumed them on the edges and the answer came out to be 70mr^2|8!
