Answer 1

Answer:

15 workers

Explanation:

1worker will complete it in(that will be 45workers×12days)

Xworkers will complete in 18days(12+6days)

we'll have

• X=(1×540)/18
• X = 540/18
• X= 30

so if 1 worker can complete the same piece of work in 540 days, then to get the workers that will complete it in 6more day(making it 12+6=18), it will be

540/(12+6)= 30workers

note; we are looking for numbers of workers that should be removed to complete it in 6more days

so we have 45-30=15

15 workers must be removed to complete it in 18days
