A thin converging lens forms a real image of an object located far away from the lens. The image is formed at A at a distance 4x from the lens and height of the image is h. A thin diverging lens of focal length x is placed at `B [PB = 2x]` and a converging lens of focal length 2x is placed at `C [PC = 3x]`. The principal axes of all lenses coincide. Find the height of the final image formed.
