Solution:

A thin walled glass container is filled with water μ=4/3. A point source S is fixed inside water. A thin equiconvex lens (µ=1.5) and concave mirror are arranged with mutual separation R/2 as shown in figure.
The distance of lens from the plane surface of the container is also R/2 for first (as shown in diagram) and R/6 for second question of the stem (assume suitable change in diagram). Here R is radius of curvature of all curved surfaces. An observer is present at the position of S itself. The distance of S from A is mR, and separation between final image seen by observer and observer himself is nR.
