On a planet oz there are 8 days apart from sunday to saturday, 8th day is oz day.Compared to earth where clock crosses each digit on clock twice, there are 36 hrs in day ,90 min in hour, 60 seconds in minute.Find the angle between clock hands on 11:40

• angle by hr hand=11*20+(4/9)*20=229
  angle mede by min hand=40*4=160
  hence req angle=229-160=69

• 360/18=20
  1)A clock with 20 degree angle btw digits( it will have 18 digits)
  2) angle btw. hour and minute hand at 11:40 is 60 degree(i.e angle btw 11 and 8 digit 3*20)
  3) It was assuming that hour hand is at 11 but hour hand must have moved forward during 40 minutes by 9 degree
  total angle =69 degree

• angle made by short hand =360/18*11 + 80/9=229
  angle made by big hand =360/90*40=160
  so angle between both hand =229-160=69 degree

• it can be solved in simple way
  in one hour hour hand traces 360/18=20deg
  minute hand in one minute = 360/90=4deg
  11 hours 40 minutes = (11+ 40/90)hours =103/9 hours
  so angle traced by hour hand = (103/9)*20= 228.888=229 approx
  angle traced by minute hand = 40*4= 160deg
  hence 229-160=69deg :)
