Question 189290: Sam can do a job in 4 days that Lisa can do in 6 days and Tom can do in 2 days, how long would the job take if Sam, Lisa, and Tom worked together to complete it? Answer by jonvaliente(64) (Show Source):
You can put this solution on YOUR website! Let x = no of days to complete the job
1/x = amount of work done in 1 day
Multiply both sides by 12
Multiply both sides by x
Divide both sides by 11
It would take 1 1/11 days to complete the job.
