Question

2 people can complete a work in 12 days How many days will 20 people take for completing the Same work​

Answer 1

A job takes 12 days to get completed by 2 men.

1 task = (12 days) x (2 men) = 24 man-days.

Therefore, the job requires 24 man-days to get completed. In other words, it would take 24 days for a man to complete the job.

Now, if you have 20 men, how many days would take to complete the same job?

1 task = (X days) x (20 men) = 24 man-days

X = (24 man-days) / (20 men)

X = 1.2 days
