QUESTION: 1

Earliest Date = 20 weeks 
Latest Date = 40 weeks


Activity E is connecting both the events and its duration is 10 weeks. The independent float of the activity is

Solution:

Independent float

QUESTION: 2

The network rules are common to ail activity on- arrow networking systems. The use of computers for making computations may impose certain rules. Which of the following basic rules of network logic are correct?
1. Before an activity may beg in, all the activities preceding it must be complete.
2. Any two events may be directly connected by not more than one activity.
3. Event numbers must not be duplicated in a network.
Select the correct answer using the codes given below:

Solution:
QUESTION: 3

Match List-I (Item) and with List-ll (Characteristic) and select the correct answer using the codes given below the lists:

Codes:

Solution:
QUESTION: 4

A father notes that when his teenage daughter uses the telephone, she takes not less than 6 minutes for a call and some times as much as an hour. Fifteen minutes call are more frequent than calls of any other duration. If these phone calls were an activity in PERT project, then phone calls expected duration will be

Solution:


∴ 
= 21 minutes

QUESTION: 5

Consider the following statements:
1. A dummy activity is artificially introduced in a network when necessary,
2. A dummy activity consumes some time.
3. A dummy activity is represented by a dotted arrow.
4. A dummy activity must necessarily be introduced in every network.
Which of the above statements are correct?

Solution:

A dummy is introduced artificially and it is shown by a dotted arrow. It does not consume any time. It is not necessary to introduce a dummy always. Thus statements 1 and 3 are correct.

QUESTION: 6

Match List-I (Activity type) with List-ll (Representation by) and select the correct answer using the codes given below the lists:

Codes:

Solution:

A-4, B-1.C-2, D-3
Artifically introduced activity is dummy and it is shown by a dotted arrow.
Critical activity is represented by a single thick arrow.
Non-critical activity is represented by a single arrow. Dangler does not enter into any event.

QUESTION: 7

With reference to the network shown in figure, which statement is incorrect?

Solution:

Because dummy activity between events 3 and 7 imposes a restriction on the occurrence of event 7 unless event 3 also occurs.

QUESTION: 8

Figure shows the network for a particular project which consists of four activities.

Normal duration time and crash time for each activity are given below:

The minimum time required for the completion of project is

Solution:

This is the sum of crash times along the critical path.

QUESTION: 9

In PERT analysis, event means

Solution:
QUESTION: 10

Consider the following statements:
1. Tests on cement paste to determine initial and final setting times are done at normal consistency condition.
2. Low heat cement has a high percentage of tricalcium aluminate.
3. High early strength Portland cement contains a larger percentage of tricafcium silicate and a lower percentage of dicalcium silicate.
Which of these statements are correct?

Solution:
