10 - 18 machines complete a job in 40 days
So, 18  +  6  =  24 machines complete the job in 40 x 18 / 24  =  30 days
Number of days saved  =  40  -  30  =  10 days

If 18 identical machines required 40 days to complete a job, how many fewer days would have been required to do the job if 6 additional machines of the same type had been used from the beginning?
