If 25 workers can complete a job in 40 days, how many workers are needed to complete the job in 25 days?
Q1. If 25 workers can complete a job in 40 days, how many workers are needed to complete the job in 25 days?
Answer: 40 workers
Explanation: The work done is constant, so the product of the number of workers and the days to complete should be constant. 25 workers * 40 days = 1000 worker-days. To complete in 25 days: 1000 / 25 = 40 workers.
