The correct clock's minute hand gains over its hour hand in actual 65 minutes = 65*55/60 min.
The incorrect clock's minute hand gains over its hour hand in actual 65 minutes = 60 minutes.
So the net gain of the incorrect clock over the correct clock in actual 65 minutes = 60-[65*55/60] = 5/12min.
so, in 24 hours it will gain = 5/11 * (24*60/65) = 10.97min (Ans)
