  Official UPSC Civil Services Exam 2016 Prelims Part B
  
  ## Solution:
  
  11:00 am to 2:27 pm → 3 hours 27 minutes
  3 hours 27 minutes = 207 minutes
  Now, an interval of 5 minutes is scheduled after each period. So, there will be an interval after the first period, after second period and after the third period. There will be no interval after the fourth period.
  Hence, total duration of classes = 207 - 15 = 192 minutes
  Therefore, duration of each period = 192 ÷ 4 = 48 minutes
  
  Hence, the duration of each class is 48 minutes.
