Consider the given project network, where numbers along various activities represent normal time. The free float on activity 4-6 and the project duration, respectively, are
-
- 2 and 13
- 0 and 12
- –2 and 13
- 2 and 12
Correct Option: A
For 4 – 6
Free float = (Ej – Ei) – dij
= (8 – 2) – 4
= 6 – 4 = 2
Project duration, E = 13
∴ (2, 13)
