A point object O is placed at a distance of `20 cm` from a convex lens of focal length `10 cm` as shown in the figure. At what distance x from the lens should a convex mirror of focal length `60 cm,` be placed so that final image coincide with the object?

`10 cm`

`40 cm`

`20 cm`

Final image can never coincide with the object in the given conditions
