It is given that they awarded 72 people.
It is also known that if they would have awarded 3 more people ,3/5th of the total workforce is given bonuses.
So it follows:
[tex]\begin{gathered} 72+3=\frac{3}{5}\times x \\ 75\times\frac{5}{3}=x \\ x=125 \end{gathered}[/tex]So the total workforce is 125 people.
