उत्तर
Given: A, D, E can start simultaneously.
A < B, C; C, D < G, F; E, F < H
Working rule:
A < B, C implies activity A is the immediate predecessor of activities B and C.
i.e., for activities B and C to occur, activity ‘A’ has to be completed.
Similarly, for activities G, F to occur D and C has to completed for activity H to occur E and F has to be completed.
∵ A, D and E are independents events.
