  • The clock loses 30 minutes per hour.
    i.e 30 minutes of this faulty clock = 60 minutes of the correct clock
    From 2 p.m to 6 p.m ,
    total number of hours = 4 hours
    4 hours of this faulty clock => 4 x 60/30= 8 hours of original clock
    So, The correct time when the clock show 6 p.m = 6 p.m + 4 = 10 p.m
    But The clock stopped 3 hours ago ,
    So present time is 10 p.m + 3 hours = 1 a.m
