In the dial of a clock, lines are marked instead of numbers. Observing through a plane mirror the time appeared to bt 7.25. What was the actual time ?

An object is placed at a certain depth from the upper surface of a liquid. When it is seen from air, it appears that the object is raised through (1)/(3) of the depth. Again if water is taken instead of the liquid it appears that the object is raised above through (1)/(4) of the real depth. Refractive index of liquid = (3)/(2) and refractive index of water = (4)/(3) . Explain the matter.
