The angle between the minute hand and the hour hand of a clock when the time is 8.30, is:


A. 80º
B. 75º
C. 60º
D. 105º

• total angle = 360
  angle b/w hour is 360 /12=30
  so angle at 8:30 is 60

  M=[5X-(D/6)]*12/11
  
  where,M=min,X=hour,D=angle
  Hence,
  30=[5*8-(D/6)]*12/11
  or,D/6=40-55/2
  or,D=25/2*6
  or,D=75

• 75°
  Use shortcut 30H - 5.5M
  Here H=8, M=30
  240-165=75
