Question

If 24 men can finish a piece of work in 30 days. How many men will be needed to finish it in 45 days.​

Answer 1

Answer:

It will take 30 days for 36 men to complete the job.

1. One forty-fifth of the job is completed in 1 day. One 1/45 = 0.0222, or 2.22%.

2. If there are 24 men working, then each man completes 0.0925% of the job in 1 day (2.22% / 24 = 0.0925%)

3. At that rate (0.0925% completed by one man in one day), 36 men can complete 3.33 % of the job in 1 day (0.0925% x 36 = 3.33%)

4. If 3.33% of the job is completed in one day, then the job will be 100% complete in 30 days (100% / 3.33% = 30)
