Solution

The correct option is B
False

As the number of workers increases, the number of days required for the work to be completed decreases. This is an inverse proportion condition.

Let the required number of days be n

$16 \times 10 = 4 \times n$

$n = 40$

So, 40 workers are required to finish the work in 4 days.
