12 workers completed work in 40 days
----------------------------------
10 times as many workers can do the work in 1/10 of that time, or
120 workers can complete work in 4 days
------------------------------------
1/4 that many workers will take 4 times as long to complete work, or
30 workers can complete work in 16 days
-----------------------------------
You can also say that
( number of workers ) = k*( 1 / number of days to complete work )
( this is an inverse variation )

Now let = number of workers
