Question

7 people need 100 days to repair and paint heritage building if the job should be completed in 25 days how many more people need to be employed

Answer 1

We'll use Unitary Method in this case:-

$\frac{7}{100} = \frac{x}{25} \\ = x = 28$

Considering the number of people as x, 28-7 = 21 more people need to be employed.
