Answer 1

Answer:the answer is 3 days pls mark me as genius

Step-by-step explanation:

Answer 2

Let the time taken to complete the job be x.

Here the number of persons and the number of days are in inverse proportion.

$\therefore\frac{3}{4}=\frac{x}{4}$

$\Rightarrow\frac{4\times3}{4} = x$

$\Rightarrow\frac{12}{4} = x$

⇒ x = 3

They will complete the job in 3 days.
