    The project network is shown below:

    The project completion path is along A-C-E or B-D-E

    Duration along path A-C-E = 2 + 1 + 3 = 6

    Duration along B-D-E = 4 + 6 + 3 = 13

    Since, longer time is along B-D-E,

    The critical path for the network activities is along B-D-E with duration 13.
