The focal lengths of objective lens and eye lens of a Gallelian Telescope are respectively $\displaystyle 30$ cm and $\displaystyle 3.0$ cm. Telescope produces virtual, erect image of an object situated far away from it at least distance of distinct vision from the eye lens. In this condition, the Magnifying Power of the Gallelian Telescope should be :
