If 4 workers take 6 days to complete a project, how many days would 8 workers take?

Explanation:
Work is completed in proportion to the number of workers when each person contributes equally, and the total amount of work is fixed. If 4 workers take 6 days, the total effort is 4 × 6 = 24 worker-days. With 8 workers, the same 24 worker-days of work require 24 ÷ 8 = 3 days. Doubling the workforce halves the time, assuming constant productivity and no added delays. So it would take 3 days.
