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
