Two discs of same mass and different radii are made of different materials such that their
thicknesses are $1 \mathrm{~cm}$ and $0.5 \mathrm{~cm}$ respectively. The densities of materials are in the ratio $3: 5$. The
moment of inertia of these discs respectively about their diameters will be in the ratio of $\frac{x}{6}$. The
value of $x$ is ________.
