Mirror Images - Clocks
There are certain questions in which the positions of the hour - hand and the minute - hand of a clock as seen in a mirror are given. On the basis of the time indicated by the mirror - image of the clock we have to detect the actual time in the clock. In the solution of such questions, we use the fact that if an object A is the mirror - image of another object B then B is the mirror - image of A. The method of solving such questions would be clear from the following example.
