A clock is attached to a wall. Below the clock a mirror is placed. When seen through a mirror, the clock shows 6 : 45. The correct time is

Explanations: The correct time is 5:15

Detailed Solution for NATA Mock Test - 9 - Question 21

When you view a clock in a mirror, the reflection shows a reversed image of the actual time.

To find the correct time when the mirrored image shows 6:45:

• Subtract the minutes shown from 60 to find the actual minutes. 60−45=15
• Subtract the hour shown from 12 to find the actual hour. 12−6=6 Since 6:45 is being viewed in a mirror, it actually means: 6−1=5

So, the mirrored image of 6:45 corresponds to the actual time of 5:15.
