ITPEC IP October 2018 Question 52
ITPEC IP October 2018 — Question 52 of 100
Activity C to F can be delayed by at most 4 days without extending the project. The critical path A-B-D-F-G takes 3+4+6+4=17 days. The path containing C-F, A-C-F-G, takes 3+6+4=13 days, leaving 17-13=4 days of total float.
Answer (d)
Why not others:
- delays of 1, 2, or 3 days are possible but are not the maximum
- a delay beyond 4 days makes the C-F path longer than the 17-day critical path
Key rule: An activity's allowable delay is its float: the difference between the project duration and the longest relevant path containing that activity.
