What will be the minimum time required to deliver a parcel at Kharagpur office from Jamshedpur station and come back to Jamshedpur station?
Explanation:
For the minimum time, the employee must start from Jamshedpur in train number T102 at 7:30 and reaches Kharagpur at 9:05. Total journey time t1 = 1 hours 35 minutes Then he takes 90 minutes in all to go from station to the office, complete the paperwork and come back to the Kharagpur station. So he reached the station at 10:35. The earliest train from Kharagpur to Jamshedpur leaves at 10:40 so the employee will have to wait for 5 minutes at the station. He takes the 10:40 train and reached Jamshedpur at 12:35. Journey time t2 = 1 hour 55 minutes Total time = t1 + 90 + 5 + t2 = 5 hour 5 minutes Hence, the correct answer is option 2.
