The correct Answer is:
To find the time shown by the image of a wall clock in a plane mirror, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Clock Time**: The given time on the clock is `04:25:37`, which means: - Hours = 4 - Minutes = 25 - Seconds = 37 2. **Calculate the Total Time in Seconds**: Convert the time into seconds for easier manipulation. - Total seconds = (Hours × 3600) + (Minutes × 60) + Seconds - Total seconds = (4 × 3600) + (25 × 60) + 37 - Total seconds = 14400 + 1500 + 37 = 15937 seconds 3. **Determine the Mirror Time**: In a mirror, the hour hand reflects the time as if the clock were reversed. The total time in seconds for a full 12-hour cycle is 12 hours = 43200 seconds. To find the mirror time, we subtract the total seconds from 43200 seconds. - Mirror time in seconds = 43200 - 15937 = 27263 seconds 4. **Convert the Mirror Time Back to Hours, Minutes, and Seconds**: - Calculate hours: - Hours = 27263 ÷ 3600 = 7 hours (since 27263 seconds is more than 7 hours but less than 8 hours) - Remaining seconds = 27263 - (7 × 3600) = 27263 - 25200 = 1063 seconds - Calculate minutes: - Minutes = 1063 ÷ 60 = 17 minutes - Remaining seconds = 1063 - (17 × 60) = 1063 - 1020 = 43 seconds 5. **Final Result**: Therefore, the time shown by the image of the clock in the mirror is `07:17:43`. ### Summary: The time shown by the image of the clock in a plane mirror is **07:17:43**.

To find the time shown by the image of a wall clock in a plane mirror, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Clock Time**: The given time on the clock is `04:25:37`, which means: - Hours = 4 - Minutes = 25 - Seconds = 37 ...
