Moment of inertia of a disc of mass $\displaystyle M$ and radius ' $\displaystyle R$ ' about any of its diameter is $\displaystyle \frac{\mathbf{M R}^2}{4}$. The moment of inertia of this disc about an axis normal to the disc and passing through a point on its edge will be, $\displaystyle \frac{x}{2} \mathrm{MR}^2$. The value of $\displaystyle x$ is $\displaystyle \_\_\_\_$.
