If a certain job can be performed by 18 workers in 26 days, the number of workers need to perform the job in 12 days is?
- 45
- 39
- 24
- 30
Explanation
Work = Force x Time
Since the work remains the same, we can set up a proportion:
18 workers x 26 days = x workers x 12 days
To solve for x, we can cross-multiply:
18 x 26 = x x 12
468 = 12x
Now, divide both sides by 12:
x = 468 / 12
x = 39
So, the correct answer is: 39 workers
