Question

A construction project consists of five activities. The immediate successor activity relationship and duration of each activity are mentioned.

Find the total duration of the project in weeks.

Hint:

Critical Path Method (CPM) calculates the total project duration by determining the longest sequence of dependent tasks.

Answer 1

Correct Answer: 12

From the table: \[ P \rightarrow R \text{(2 weeks)} \] \[ Q \rightarrow R \text{(4 weeks)} \] \[ R \rightarrow T \text{(5 weeks)} \] \[ S \text{(6 weeks)} \] \[ T \text{(3 weeks)} \] Using the critical path method, the total duration = 12 weeks. Thus, \[ \boxed{12} \]
