Question

if 100 workers can complete a work in 20 days how many workers needed to complete work in 10 days​

Answer 1

Answer:

200 workers

Step-by-step explanation:

Let, X workers needed to complete work in 10 days​

100 workers can complete a work in 20 day

:. 100 workers can complete $\frac{1}{20}$ part of work in a day

:. 1 worker can complete = $\frac{1}{20*100}$ = $\frac{1}{2000}$ part of work in a day

:. 1 worker can complete = $\frac{1}{2000}*10$ = $\frac{1}{200}$ part of work in 10 days

:. To complete work in 10 days​ =  $\frac{1*1}{\frac{1}{200} }$ = 200 workers needed
