In the network showrr in the figure the activity 4-5 can be started only when

According to Fulkerson’s rule, what are the correct event numbers corresponding to events A, B, C, D,E, Fand G respectively of the network shown in the figure below?

The given figure shows the arrow diagram for a particular project. The arrow A is known as

A ‘merge event’ is represented by

Consider the following statements:
The critical path in a network plane of a project
1. help in planning efficient time schedule
2. indicates the shortest path in time
3. helps in crashing the project judiciously 
4. helps in encouraging discipline in execution
Which of these statements are correct?

Match List-1 (Description of activity floats) with List-11 (Names of the floats) and select the correct answer using the codes given below the lists:
List-I
A. Earliest start time of its successor activity minus earliest finish time' of the activity in question minus the duration
B. Time available for an activity performance minus the duration of the activity
C. Excess of minimum available time over the required activity duration
D. Difference between total float and free float of an activity

For an activity i-j, the early event times at i and j, respectively are 5, 24, 9 and 29. (EST = 5, LST = 9, EFT = 24, LFT = 29. The activity duration is 6. Match List-I (Float) with List-ll (Duration) and select the correct answer using the codes given below the lists:
List-I                        List-ll
A. Free                    1. 5
B. Total                    2. 9
C. Interfering           3. 13
D. Independent       4. 18
Codes: A, B, C, D

Consider the following statements:
CPM network helps an engineer to
1. Concentrate his attention on critical activities
2. Divert the resources from non-critical advanced activities to critical activities
3. Be cautious in avoiding any delay in the critical activities in order to avoid delay of the whole project
Which of these statements are correct?

Consider the following features/factors:
1. Projects are of. the non-repetitive type.
2. Time required .need not be known.
3. Time required is known precisely.
4. Emphasis is,giyen to activities of project.
5. Events have been established for planning.
For which of these features/factors PERT is preferred for planning ?

The flow net of activities of a project is given in the following figure. The duration of activities are indicated along the arrows. The critical path of the activities is along
