  • Options
  • A. 80 Degrees
  • B. 75 Degrees
  • C. 60 Degrees
  • D. 105 Degrees

  • Correct Answer
  • 75 Degrees 

    Explanation

    Angle traced by hour hand in 17/2 hrs =  360 12 × 17 2 o = 255 

     

    Angle traced by min hand in 30 min =  360 60 × 30 o  = 180 

     

    Therefore,  Required angle = (255 - 180) =  75 o
