Each day on Planet M is 10 hours, each hour 60 minutes and each minut...
To solve this question, we need to understand the time system on Planet M and how it relates to the time shown on the clock.

Time System on Planet M:
- Each day on Planet M is 10 hours.
- Each hour on Planet M is 60 minutes.
- Each minute on Planet M is 40 seconds.

Time Shown on Clock:
The time shown on the clock is 3 hours 42 minutes and 20 seconds in a mirror. This means that the reflection of the clock is shown, which means that the hour hand and the minute hand are interchanged. Therefore, the hour hand is pointing at the 42-minute mark and the minute hand is pointing at the 3-hour mark. The second hand is irrelevant for this question.

Solution:
We need to find the time on Planet M exactly 5 minutes after the time shown on the clock.

1. Convert the time shown on the clock to the time on Planet M:
- The hour hand is pointing at the 42-minute mark, which corresponds to 42 minutes on Planet M.
- The minute hand is pointing at the 3-hour mark, which corresponds to 3 hours on Planet M.

2. Add 5 minutes to the time on Planet M:
- Since each minute on Planet M is 40 seconds, adding 5 minutes is equivalent to adding 5 * 40 = 200 seconds.
- Therefore, the time on Planet M after 5 minutes is 3 hours 42 minutes + 200 seconds.

3. Convert the time on Planet M back to the time shown on the clock:
- Since each minute on Planet M is 40 seconds, we need to divide 200 seconds by 40 to find the equivalent number of minutes. 200/40 = 5 minutes.
- Therefore, the time shown on the clock after 5 minutes is 3 hours 42 minutes + 5 minutes = 3 hours 47 minutes.

4. Convert the time shown on the clock to the time on Planet M:
- The hour hand is pointing at the 47-minute mark, which corresponds to 47 minutes on Planet M.
- The minute hand is pointing at the 3-hour mark, which corresponds to 3 hours on Planet M.

5. Therefore, the time on Planet M exactly after 5 minutes is 3 hours 47 minutes.

Conclusion:
The time on Planet M exactly after 5 minutes is 3 hours 47 minutes. However, the given options do not include this answer. It seems there may be an error in the options provided.
