Answer:

18cm

Explanation: 30 cm

The coincidence is possible when the image is formed at the centre of curvature of the mirror. Only then the rays refracting through the lens will fall normally on the convex mirror and retrace their path to forma the image at the place of object.

The distance from the lens to the mirror is given as,

d=30−12

d=18cm
