A solid sphere and a hollow cylinder roll up without slipping on same inclined plane with same initial speed $\displaystyle v$. The sphere and the cylinder reaches upto maximum heights $\displaystyle \mathrm{h}_1$ and $\displaystyle \mathrm{h}_2$, respectively, above the initial level. The ratio $\displaystyle h_1: h_2$ is $\displaystyle \frac{n}{10}$. The value of $\displaystyle n$ is $\displaystyle \_\_\_\_$.
