A college starts from 10 AM continues till 1:30 PM. In this duration there are five periods. If 5 minutes are provided before each period to leave the room and enter the other, then what is the duration of each period?

a. 38 min
b. 41 min
c. 40 min
d. 42 min

• ans is 38 min
  because, before first period no need to leave the room and enter the room.
  so,for 5 periods 4 times 5 minutes break will be provided. that is 20 mins.
  10 A.M-1:30 P.M=210mins
  210-20=190
  therefore 190/5=38 mins.

• four 5 minutes breaks are needed so 4*5=20min
  total duration is 210 minutes
  duration left : 210-20=190
  duration of each period: 190/5 =38.

• c.40
  10-1:30 totally 210 mins
  210/5=45
  each class takes 45 mins without break.
  with break 40
  finally the ans is 40.

• The time difference between 10am to 1.30 pm is 3hr 30mns
  5 periods and 5 minutes break for each period that means for 5 periods 4 breaks are there so 4*5=20mns
  substract 20mns from 3hrs 30mns then u will get 3hrs 10 mins
  3hrs 10 mns means 190mns
  therefore 190/5=38
  answer is a.

• 10am to 1.30am total hrs are 3hrs.30min
  5min provided to leave & enter the room 5*5=25min, 3hrs.30min-25min=3hrs5min
  therfore 3hrs 5min/5periods====== each period duration is 61min.
  ans=61min
