Test: CPM & PERT - 2 - Civil Engineering (CE) MCQ

Consider the following network of activities, with each activity named A-L, illustrated in the nodes of the network

The number of hours required for each activity is shown alongside the nodes. The slack on the activity L, is ________ hours.

The activities of a project, their duration and the precedence relationships are given in the table. For example, in a precedence relationship "X < Y < Z" means that X is predecessor of activities Y and Z. The time to complete the activities along the critical path is ______ weeks.

Following data refers to the activities of a project, where, node 1 refers to the start and node 5 refers to the end of the project.

The critical path (CP) in the network is

A project consists of 7 activities. The network along with the time durations (in days) for various activities is shown in the figure.

The minimum time (in days) for completion of the project is_________

A sample of 15 data is follows: 17, 18, 17, 17, 13, 18, 5, 5, 6, 7, 8, 9, 20, 17, 3. The mode of the data is

The precedence relations and duration (in days) of activities of a project network are given in the table. The total float (in days) of activities e and f, respectively, are

A project has six activities (A to F) with respective activity durations 7,5,6,6,8,4 days. The network has three paths A-B,C-D and E-F. All the activities can be crashed with the same crash cost per day. The number of activities that need to be crashed to reduce the project duration by 1 day is
