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 Activity Duration (days) 1-2 2 2-3 1 4-3 3 1-4 3 2-5 3 3-5 2 4-5 4 The critical path (CP) in the network is Correct Answer 1-4-3-5

Concept:

Trick: Whenever activity is mentioned take points on node itself to avoid the confusion.

And take the duration on path.

→ Note: Find the durations of path given in option and then take the path with max duration

Because, Critical path is the minimum time required to completed the task or path with maximum duration

1) 1 – 2 – 3 – 5 = 5 days

2) 1 – 2 – 3 – 4 – 5 (No path is formed) ∵ 3 – 4 path is not a path

3) 1 – 4 – 3 – 5 = 8 days

4) 1 – 4 – 5 → 7 days

Hence from the above calculation we can see that path in the option(c) is the critical path.

A construction project consists of twelve activities. The estimated duration (in days) required to complete each of the activities along with the corresponding network diagram is shown below. Activity Duration (days) Activity Duration (days) A Inauguration 1 G Flooring 25 B Foundation work 7 H Electrification 7 C Structural construction - 1 30 I Plumbing 7 D Structural construction - 2 30 J Woodwork 7 E Brick masonry work 25 K Coloring 3 F Plastering 7 L Handing over function 1   Total floats (in days) for the activities 5-7 and 11-12 for the project are, respectively:
Statement I The critical path has been defined as the longest duration path between the first and the last nodes of a project.
Statement II The duration of a project is not always the same as the duration of its critical path.
Statement III The earliest start and finish times of an activity are based on the condition that every activity will not be started and finished as early as possible.
Find the correct answer for given statements being correct or incorrect.
Statement (I): Crashing of project duration always increases the cost of the project on its completion, no matter what the indirect, or overhead, costs are. Statement (II): The critical path along the project activities network diagram is compressed in the process of investigating the crashing of the project duration, and not the non-critical activities, up to a certain stage of crashing. 
From the given below statements, find the incorrect statement. i. A critical path has zero float. ii. A critical path has both critical and non-critical activities. iii. A critical path is the longest path and consumes maximum time and resources.
In a school, a Science project has been assigned to three students Rajat, Rohan, and Bishal and it was told that they should work together on that project. Working alone Rohan can finish the project in 20 days, it is also given that if Rajat and Bishal work on the project they will take 9 days to complete the project. Bishal alone can complete the project in 15 days. Rohan started working on the project from Monday but after 8 days he left and after that Rajat and Bishal started working on it but Bishal also left 6 days before completion of the work and Rajat completed the remaining project, in how many days will the project be completed and on which day will it be completed?
A project network comprises five activities as shown below. The activity durations. in days. are as indicated. Crashing of any activity costs Rs. 1000 per day. If the project is crashed to the shortest possible duration without changing the critical path the total crashing coso in Rs. is
