Solution

Concept: 1 Mark
Solution: 1 Mark

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

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.
