Answer:
The Correct Answer would the time 07:34:23, where 07 denotes the hour, 34 denoted minutes and 23 denote seconds. The image of the time 04:25:37 in plane mirror would be 07:34:23.
Explanation:
We can approach this question in two ways, one being practical, other being mathematical.
- for the practical method, we can just simply put a clock with above mentioned time in front of a mirror. The, looking it's reflection in the mirror and comparing it with a usual clock, we can get our answer.
- for the mathematical method, we know that there are 12 hours mentioned in a clock. Hence, the addition of anytime plus it's complement will result in time to be 12:00:00. Therefore, for the correct measurement, we will subtract the given time by 12:00:00 as per time subtraction.
Hence, the time = 12:00:00 - 04:25:37
The Answer = 07:34:23,
