Answer 2

Answer:

3000 people

Step-by-step explanation:

LET NO. OF WORKERS REQUIRED = x

   No. of people  People         1800      x

   No. of days                             40       24      

 ∴ It's inverse variation as No. of people increase No. of days decreases

1800*40 = 24x

x = $\frac{72000}{24}$

x = 3000 people

∴ No. of people needed is 3000 to complete the work in 24 days
