A work project consists of twelve activities labelled A through L. Upon being asked to specify the order in which the jobs had to be done, the manager answered as follows:

A, B, and C are the first activities of the project and can start simultaneously and immediately; A and 8 precede D while 8 precedes E, F, and H. Activities F and C precede G while E and H precede / and J. C, D, F and J precede K which, in turn, precedes L. Further, /, G, and L are the terminal activities of the project.

The completion times of the various activities are listed as follows:

(a) Draw a network diagram corresponding to this project

(b) Obtain the lengths of all the paths and determine critical path.
