and last again on 12 o'clock

The overlap does not happen exactly on 3-15, 4-20 or 5-25 and so on. For example at 3-15 the minute hand will be at 3 but the hour hand will move little ahead of 3. Same way at 6-30, the hour hand will be ahead of the minute hand, not overlapping. Formula for exact time for overlap is: 12n/11 n
