XAT 2018 — Decision Making Question 13
Answer the following question based on the information given below.
A courier service has offices at three locations: Jamshedpur, Kharagpur and Howrah. Its employees travel by trains from one location to another for pick-up and delivery. It takes 40 minutes for an employee to travel from any railway station to the nearest office (and another 40 minutes for coming back); the paperwork to deliver the parcel at the respective office takes an additional 10 minutes. Assume employees do not waste any time.
Employees have the option to choose from any trains, whose time table is given in table below. Assume all trains travel on time and there is no time gap between arrival and departure of a train. Further, assume that the employees board the trains as soon as it arrives at the station.

What will be the minimum time required to deliver a parcel at Kharagpur office from Jamshedpur station and come back to Jamshedpur station?
Answer & solution
- A
4 hours 25 minutes
5 hours 5 minutes
- C
6 hours 35 minutes
- D
7 hours 30 minutes
- E
None of the above
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.
