A bi-convex lens has radius of curvature of both the surfaces same as $1/6\mathrm{cm}$. If this lens is required to be replaced by another convex lens having different radii of curvatures on both sides $\left(R_1\ne R_2\right)$, without any change in lens power then possible combination of $R_1$ and $R_2$ is :
