Q. When the mirror image of a watch was seen, it showed 3 : 15. What was the real time ?
a) 8:45
b) 3:15
c) 9:45
d) 7:45
Correct Answer: a) 8:45
Question from UPPSC Prelims CSAT 2025
Explanation:
In a vertical mirror, the clock’s mirror time and real time add up to 12:00. Hence, Real time = 11:60 − (mirror time). Given mirror time = 3:15, so real time = 11:60 − 3:15 = 8:45.
Verification: 8:45 + 3:15 = 12:00, confirming the mirror of 8:45 is 3:15. Therefore, the real time is 08:45:00.
