Answer:

2 days

Step-by-step explanation:

Answer 2

Therefore 12 people can finish that job in 2 days.

Step-by-step explanation:

To solve time and work problem we always use the following formula

$\frac{M_1\times d_1}{W_1} =\frac{M_2\times d_2}{W_2}$

M₁,M₂= Number of workers

d₁,d₂= Number of days

w₁,w₂= Amount of work

In this case the amount of work same, i.e w₁=w₂

The formula becomes

M₁×d₁=M₂×d₂....(1)

Here, M₁=4 , d₁= 6 days, M₂= 12 and d₂=?

Putting the value of   M₁ , d₁, M₂ in (1) we get

4×6 = 12× d₂

$\Rightarrow d_2=\frac{4\times 6}{12}$

⇒ d₂=2

Therefore 12 people can finish that job in 2 days.
