Solution

The correct option is C 6 cm behind convex mirror, virtual
For concave mirror,



f=vuv+u
15=v(15)v15
v=30 cm

For convex mirror, the first image (formed by concave mirror ) acts as an object.


f=vuv+u
15=v(10)v10
v=6 cm

So the final image is formed 6 cm behind the convex mirror. (final image is virtual).
