Problem: It took 180 men working 8 hours a day for
21 days to complete a job. How many men will be
employed to complete the job in 18 days, if they
work 12 hours a day?
Solution:
, First, calculate the total man-hours required for
the job:
Total Man-
Hours=Number of Men×Hours per Day×Number of
Days\text{Total Man-Hours} = \text{Number of
Men} \times \text{Hours per Day} \times
\text{Number of Days}Total Man-
Hours=Number of Men×Hours per Day×Number of
Days Total Man-
Hours=180 men×8 hours/day×21 days=30,240 man-
hours\text{Total Man-Hours} = 180 \text{ men}
\times 8 \text{ hours/day} \times 21 \text{ days} =
30,240 \text{ man-hours}Total Man-
Hours=180 men×8 hours/day×21 days=30,240 man-
hours
Next, calculate the total man-hours available
with the new conditions:
Total Man-
Hours with New Conditions=Number of Men×12 ho
urs/day×18 days\text{Total Man-Hours with New
