Answer:

21 days

Step-by-step explanation:

3 boys can complete a work in 7 days

First we find total unit of work.

Total work = Number of worker x number of days

                  = 21 units of work

Now, 21 unit of work complete by 1 boy

Similar, total work can't be change.

Let one boy take d days to finish 21 unit of work.

                  1 x d = 21

                       d = 21 days

Hence, One boy can finish same job in 21 days.
