Let x be the number of days taken by 6 people. With more number of people working, the job will take less time to be completed. That means they are inversely proportional.

  •  People  Days
  •  20  12
  •  6  x

That is 20 × 12 = 6x or x = (20 × 12)/6

x = 40

Hence, 6 people can finish the job in 40 days.
