The output needed to complete the job is people-days.
If you do the job in 1 day, you need 144 people.

If 12 people can do a job in 12 days, then 12 people can do 1/12 of the job in 1 day, so to get the entire job done in 1 day you would need 12 times as many people. 12 times 12 is 144.

Of course, the above calculation presumes that the granularity of the subtasks is such that there are 144 different things that can be done, each taking 1 person 1 day to complete and the sum of which is the entire job. For example, it takes a woman 9 months to have a baby. By the logic in this problem, 9 women could have the same baby in one month. I don't think so.
