Question
Following data refers to the activities of a project, where, node 1 refers to the start and node 5 refers to the end of the project.
The critical path (CP) in the network is
| Activity | Duration (days) |
|---|---|
| 1-2 | 2 |
| 2-3 | 1 |
| 4-3 | 3 |
| 1-4 | 3 |
| 2-5 | 3 |
| 3-5 | 2 |
| 4-5 | 4 |
Correct answer
(B) 1-4-3-5
Solution
To find the critical path, we evaluate the duration of all possible paths from node 1 to node 5:
1.Path 1-2-5: Duration = days
2.Path 1-2-3-5: Duration = days
3.Path 1-4-5: Duration = days
4.Path 1-4-3-5: Duration = days
The critical path is the longest path, which is 1-4-3-5 with a duration of 8 days.Continue learning with Success Tracker
