Question 413595: twelve workers can complete a job in six days. after working two days four workers are transferred to a new site. instead of six das, how many are required to complete the job Answer by ewatrrr(24785) (Show Source):
Hi
twelve workers can complete a job in six days or 1/6 of job in 1 day. = 1/72 by each worker each day.
After 2 days: 4/6 of job left and 8 workers left to complete:
8/72 Or 1/9 per day = 36/6 = 6 days to complete job
