Question

The project activities, precedence relationships and durations are described in the table. The critical path of the project is

Activity	Precedence	Duration (in days)
P	-	3
Q	-	4
R	P	5
S	Q	5
T	R, S	7
U	R, S	5
V	T	2
W	U	10

• A. P - R - U - W
• B. Q - S - U - W
• C. Q - S - T - V
• D. P - R - T - V

Answer 1

The correct option is B Q - S - U - W


Possible path:

1. QSUW = 24 days $\Rightarrow$ critical path

2. QSTV = 18 days

3. PRTV = 17 days

4. PR VW = 23 days
