Answer:

250

Step-by-step explanation:

Number of labourers * Number of days worked = Total number of working days

Total number of working days to construct a 4km long road: [tex]200*50=10000[/tex]

Total mumber of working days to construct a 8km long road: [tex]10000*2=20000[/tex]

Labourers: 20000 ÷ 80 = 250.

250 labourers are required.
