Step-by-step explanation:

Answer 2

50 additional men are required.

Step-by-step explanation:

Consider the provided information.

half of the work had been done in 40 days.

So, half of the work needs to be done in 60-40 = 20 days.

In 40 days $\frac{1}{2}$ work is done by 50 men.

That means in 1 day $\frac{1}{2}$ work is done by: 50×40

In 20 days  $\frac{1}{2}$ work is done by: $=\frac{50\times40}{20} =100$

So they need total 100 employees but they already has 50.

So the additional men required are: 100-50=50.

Hence, 50 additional men are required.
