Question
The project activities are given in the following table along with the duration and dependency.
Which one of the following combinations is correct?
| Activities | Duration (days) | Depends on |
|---|---|---|
| P | 10 | - |
| Q | 12 | - |
| R | 5 | P |
| S | 10 | Q |
| T | 10 | P, Q |
Correct answer
(A) Total duration of the project = 22 days, Critical path is Q arrow S
Solution
Let's evaluate the possible paths and their durations:
1.Path P R: days.
2.Path Q S: days.
3.Path P T: days.
4.Path Q T: days.
The project duration is the maximum of these paths, which is 22 days. The critical paths are Q S and Q T. Option (A) correctly identifies the duration and one of the critical paths.Continue learning with Success Tracker
