Question
The mirror image of a clock shows a time of 02:44 hrs.
What is the time shown in the clock?Solution
The logic followed here is as follows, 1) If the time is between 1 and 11 then to find the actual time, the given time is subtracted by 11:60. 2) If the time is between 11 and 1 then to find the actual time, the given time is subtracted by 23:60. As, the time is between 1 and 11, so, the given time is subtracted by 11:60. 11:60 - 2:44 = 09:16 So, the time shown in the clock is 09:16 hrs.
