A lamina is made by removing a small disc of diameter 2R from a bigger disc of uniform mass density and radius 2R, as shown in the figure. The moment of inertia of this lamina about axes passing through O and is $$I_O$$ and $$I_P$$, respectively. Both these axes are perpendicular to the plane of the lamina. The ratio $$\frac{I_P}{I_O}$$ to the nearest integer is
