How much faulty it was?
A clock loses 10 minutes in every hour that means for 60 real minutes it shows 50 minutes. In another words, real time is 60/50 = 1.2 times the minutes shown by the slower clock. It was set correctly at noon & at 3:00 PM ; 180 minutes of slower clock elapsed. That means the real time is 180 x 1.2 = 216. So it's 3:36 PM in real time clock!
