Step-by-Step Solution
The complete worked solution.
Every step explained - no skipped algebra.
When a clock with only dots at 3, 6, 9, and 12 positions is kept upside down in front of a mirror and the reflection reads 6:10, the actual time is calculated by considering both the upside-down rotation and mirror reflection effects. The actual time corresponding to the reflected 6:10 is 12:20.
