Question 506379: Harold and Jim together can do a job in six days. Harold can do the job working alone in eight days. How long does it take Jim to do the job working alone?

Answer by Maths68(1474) (Show Source): You can put this solution on YOUR website!
Work rate Together (Harold + Jim) = 1/6
Harold (work rate) = h = 1/8
Jim (work rate) = j = ?
Harold (work rate) + Jim (work rate) = Work rate Together (Harold + Jim)
1/8 + j =1/6
j=1/6-1/8
Taking LCM
j=[(1*4)-(1*3)]/24
j=(4-3)/24
j= 1/24
j=one job / 24 days
Jim can do the job working alone in 24 days.
