Question

4 people can complete the work in 16 days then how many days takes to complte by one person

Answer 1

Hey mate

No.of people 4 1
No. of days 16 y

No.of days and people are in inverse proportion.

$\frac{x {}^{1} }{x {}^{2 } } = \frac{y {}^{2} }{y {}^{1} }$
$\frac{4}{1} = \frac{y}{16}$

y=16×4= $\boxed{64}$

If one person do same work then 64 days taken
