Question
A project starts with activity A and ends with activity F. The precedence relation and durations of the activities are as per the following table:
The minimum project completion time (in days) is ____________.
| Activity | Immediate predecessor | Duration (days) |
|---|---|---|
| A | - | 4 |
| B | A | 3 |
| C | A | 7 |
| D | B | 14 |
| E | C | 4 |
| F | D, E | 9 |
Correct answer
30 to 30
Solution
To find the minimum project completion time, we identify the critical path (the longest path from start to finish).Possible paths:
1.Path A-B-D-F: days.
2.Path A-C-E-F: days.
The longest path is A-B-D-F with a duration of 30 days. Therefore, the minimum project completion time is 30 days.Continue learning with Success Tracker
