Question 6

Direction: In the following question consists of two statements Assertion(A) and Reason(R). You have to read the statements carefully and select the answers to these questions using the options below.

Assertion (A): I-section is preferred to rectangular section for resisting bending moment.
Reason(R): in I-section more than 80% of bending moment is resisted by flanges only.

Question 7

Statement (I): Price escalation clause is inserted in all contracts irrespective of contract amount.

Statement (II): The rationale for price escalation clause is to compensate the contractor due to fluctuation in cost of material, fuel and labour.

Question 8

A small project, consists of seven activities in the activity on node diagram as shown in the figure above.

The duration of these of activities, in days and the predecessor relationship are shown.

What is the minimum duration in days required to complete the entire project?

Question 9

A linear project in split into six identical activities each having a, m, and b durations of 14, 18 and 20 days, which results in the standard deviation of the duration for the complete project beings x₁ days. As an alternative attempt at project planning, The earlier six activities are clubbed as (1^st and 2^nd), (3^rd and 4^th) and (5^th & 6^th), Thus, needing to consider only three (now modified) activities and the standard deviation of the duration for the complete project is now repeated as X₂ days. What will be the ratio

?

Question 10

In the following project network, free float for activity 5-6 is?
