clarification. (Question: 76132.0 )

if reflex angle is 201 that means other angle is 159( angle between hour and minute hand), are you seriious(150+9 degree only) that means that from 11 to 12 hour hand has only moved 9 degree out of 30 degree and the rest distance which an hour hand is to move for equal distance for which it move only 9 degree is 21 degree( as minute hand is to cover the rest 30 minutes and at that time hour hand is supposed to be at 12)? clear your concept please you are misguiding with so much of wrong answers.
and i know you will somehow try to subdue my explanation stating your answer is correct. but it is not sorry.

Question:

The reflex angle between the hands of a clock at 11:30 is?

Options:

A) 200^o

B) 195^o

C) 300^o

D) 360^o

Solution:

At 11:30, the minute hand is at 6 and it makes an angle = 6*30 = 180 deg from 12.

At 11:30, the hour hand is between 11 and 12 and it makes an angle = (11*30)+(30*30)/60 = 330+15 = 345 degree.

At 11:30, the minute hand and the hour hands make an angle = 345–180 = 165 deg from 12. And the larger reflex angle = 360–165 = 195 degree.
