5. A class starts at 11:00 am and lasts till 2:27 pm. Four periods of equal duration are held during this interval. After every period, a rest of 5 minutes is given to the students. The exact duration of each period is :

Correct Answer: (b) 48 minutes
Solution:Total duration of the class from 11:00 am to 2:27 pm = 3 hr 27 min = 207 minutes

So, there will be 3 rest in 4 periods.

∴ Rest time = 3 × 5 = 15 minutes

Remaining time = 207 - 15 = 192 minutes

There 192 minutes will divide in 4 equal duration period.

∴ Exact duration of each period = 192/4 = 48 minutes
