In a certain planet in a clock there was 18 hours in stead of 12. So what would be the angle between hour hand and minute hand when the time is 15:50;
Sorry forgotten the options

• In new system-
  Minute hand covers 360 degree in 90 minutes (18 x 5) .
  Hence, Minute hand covers 4 degree ( 360/90) per minute.
  
  Hour hand covers 360 degree in 18 hours.
  Hence, hour hand covers 20 degree (360/18) per hour.
  OR, Hour hand covers 2/9 degree (20/90) per minute.
  
  Now time is - 15 : 50
  The Minute hand would have covered a total of 200 degree (50 x 4) in 50 minutes.
  Similarly , The hour hand would have covered a total of 311.12 minutes [15 x 20 + 50 x (2/9) ] .
  
  Hence the angle b/w the hands is 311.12 - 200 = 111. 12 degree.

• In new system hour hand covers 360 degrees in 18 hours.
  So 15hr covers 300 degrees [(360/18)*15]
  
  Also minute hand covers 360 degrees in 60 min{since minute hand system is not mentioned in the question)
  So minute hand covers 300 degrees in 50 min.[(360/60)*50]
  
  So the angle between the hands is 0 degrees.

• @Shravan How can u say Minute hand covers 360 degree in 90 minutes ???
  it is not mentioned anything about minutes.
  We have to use 60 minutes if nothing is given.
