Question
The critical path of the following network is
Options
1 - 2 - 4 - 5
1 - 3 - 5
1 - 2 - 3 - 5
1 - 2 - 3 - 4 - 5

Solution
1 - 2 - 3 - 4 - 5
Explanation:
1 - 2 - 4 - 5 ⇒ EFT = 20 + 12 + 10 = 42
1 - 3 - 5 ⇒ EFT = 25 + 8 = 33
1 - 2 - 3 - 5 ⇒ EFT = 20 + 10 + 8 = 38
1 - 2 - 3 - 4 - 5 ⇒ EFT = 20 + 10 + 5 + 10 = 45
