Radius of cur...

Question

Radius of curvature of each surface of an equivalent lens $(μ = 1.5)$ is 30 cm. One of the surfaces is silvered from outside to make it reflecting. An object is placed in front of the silvered lens at such a position that the image formed coincides with the object. Distance of the object from the lens is :
