Project Management Professional (PMP) Exam Practice – Question1396

An activity has an early start date of the 10th and a late start date of the 19th. The activity has a duration of four days. There are no non workdays. From the information given, what can be concluded about the activity?


A. Total float for the activity is nine days.
B. The early finish date of the activity is the end of the day on the 14th.
C. The late finish date is the 25th.
D. The activity can be completed in two days if the resources devoted to it are doubled.

Correct Answer: A

Explanation:

Explanation:
Total float or slack is computed by subtracting the early start date from the late start date, or 19 -10 = 9. To compute the early finish date given a duration of 4, we would start counting the activity on the morning of the 10th; therefore, the activity would be
completed at the end of day 13, not 14 (10, 11, 12, 13). If we started the activity on its late start date on the morning of the 19th, we would finish at the end of day 22, not 25. Insufficient information is provided to determine whether this activity can be completed in
2 days if the resources are doubled.
