• 22 times hands will be vertically opposite to each other i.e. at an agle of 180 degree.
  and other 22 times hands will be overlapping each other i.e. at an angle of 0 degree.
  
  for vertically opposite. (approx)
  12:30, 1:35, 2:40, 3:45, 4:50, (5:55or 6:00), 7:05, 8:10, 9:15, 10:20, 11:25 and then again 12:30 and so on... 11*2=22 times
  
  similarly when at 0 degree angle to each other (approx)
  12:00, 1:05 and so on.... 22 times
  
  so total it will be 22+22= 44 times

• In 12 hrs total no of opposite of HR HAND & MIN HAND is 12 times(bt coincidence is 11 times as between 11 & 12 no coincidence ), so a total of 24 times opposite in 24 hrs(22 times coincidence in 24 hrs)
