    8 people working 4 hours a day will take 15 days to complete the work.

    Step-by-step explanation:

    The problem can be  solved using chain rule

    no of people      no of hours    no of days

           5                          6                    16

           8                           4                     ?

    number of days decreases when the number of people increases from 5 to 8. The decrease of number of hours from 6 to 4 increases the number of days taken for the work to get completed.

    [tex]no\ of\ days\ taken\ when\ 8\ people\ work\ 4\ hours\ a\ day=16\times 6/4\times5/8\\=480/32=15[/tex]

    8 people working 4 hours a day will take 15  days to complete the work.
