Where is 'it said'? If the sphere is hollow then how thick are the walls?
Think of a bubble.

I agree that image formed depends on the thickness of sphere.I just want to know how is it different from that formed in solid sphere.

I did wonder about that. Classmates are not always a good source of good info.
Starting with a solid sphere, you can use this link to work out the point where a distant object (the Sun, for instance) will be focussed at an approximate focal point. The distance will depend on the material used (refractive index). As the hollow centre gets bigger, the focus will be further away until there is no focussing effect for a very thin shell.
