network diagraom us shown below:
Q-A) Expected project completion time = 51hrs.
Option - B
Q-B)
Duble line shows critical path, ES=LS & EF = LF
Critical path is B-D-F-I-J
Option -A
Q-C)
Slack of activity A
Slack of the activity = LF-EF = 7-2 =5
Slack of the activity = LS-ES = 5-0 =5
Option -B
Q-D)
Earliest Start Time of Activity J is 39hrs.
