required to finish same work.​

Answer 1

Answer:

6 days

Step-by-step explanation:

two ways to solve...

1. lets assume they are doing 8*9*12 unit of work totally that is 864

Now 864 unit of work will done by 24 people working 6 hours a day in 864/24*6= 6

so 6 days are needed.

2. by formula

12*8*9=24*6*x

where assume x as number of days

so x would be 6

basic formula

efficiency*time=work

mark me as brainliest :)
