Question

An object is placed at a distance of 40 cm from a convex lens of focal length 20 cm . On the far side of the lens, a concave mirror of focal length 10 cm is placed such that the distance of the object from the concave mirror is 100 cm . Then the final image which is formed after refraction from the lens, reflection from the mirror and again refraction from the lens, will be, at a distance of 40 cm from the lens and of the same size of the object, at a distance of 20 cm from the lens and of the same size of the object, at a distance of 20 cm from the lens and of half the size of the object, at a distance of 40 cm from the lens and of half the size of the object
