An ordinary analog Clock seen through a mirror shows the time as Quarter past Nine. What will be the correct time at that instant?

3:45

2:43

2:45

3:42

✅ Correct Option: 3

When an analog clock is viewed through a mirror, the image is horizontally flipped. The mirror image shows 9:15 (Quarter past Nine).

For an analog clock viewed in a mirror, the actual time can be found using:

Actual time = 11:60 - Mirror time

This works because the mirror reverses the clock face horizontally around the 12-6 axis.

Mirror time shown: 9:15

Converting to find actual time:

Hours: $11 - 9 = 2$

Minutes: $60 - 15 = 45$

Actual time = 2:45

Therefore, the correct time is 2:45.

The answer is Option 3: 2:45
