I think it's not answerable by only knowing the job duration. The job of the long term scheduler is to choose a good mix of I/O bound and CPU bound processes, and here the information about what kind of processes are present is not given.

@srestha The long term scheduler chooses such processes so that the CPU utilisation is higher.
