Answer : 12.5 degree .
Explanation :
Analog clock is 360 degree. For 60 minutes the hour hand will move 30 degree. So for 30 minutes the hour hand will move 15 degree.
30 min = 15 degree
25 min = x degree
25/x = 30/15
x = 25 x (15/30)
x = 12.5 degree
Hence for 25 minutes the hour needle will move 12.5 degree.
