• in correct clock, minute hand gains 55 minutes spaces over hour hand.To meet with hour hand second time it has to gain 60 minutes over hour hand so
  
  55 minutes in 60 minutes
  60 minutes gain in -----(60/55)*60=3600/55
  means in every 65 minutes it gains 5/11 minutes

• 55 min. spaces are covered in 60 min.
  
  60 min. spaces are covered in (60x60)/55 min. = 65.5/11 min.
  Loss in 64 min. =(65.5/11 - 65) = 5/11 min.
