An object `O` is kept in air and a lens of focal length `10 cm` (in air) is kept at the botton of a container which is filled upto a height `44 cm` by water. The refractive index of water is `4//3` and that of glass is `3//2`. The botton of the container is closed by a thin glass slab of refractive index `3//2`. Find the distance (in `cm`) of the final image formed by the system from botton of container (refer to figure shown below).
