Explanation: Pareto principle identifies the key issues that should be fixed to resolve 80% of the problems. In this case, if the first 3 issues are fixed, that fixes 80% of the support issues.

15 B
Explanation: The time taken for each of the paths is as follows:
ABCDE?5d+5d+2d+1d=13d
AFGCDE?2d+3d+1d+2d+1d=7d
AHIDE?3d+6d+3d+1d=13d
Since AHIDE and ABCDE take the same time to complete and are the longest paths, they are the critical paths for this project. Total float is 0 on the critical path.

Explanation: 
Initial estimate=$5000
Incentive promised if performance conditions are met=$1000
Overage=20% of $5000=$1000
Agreement between buyer and seller was to share the departure from original estimate at a pre-determined rate of 70 (buyer)/30 (seller).
70% of overage=$700
Seller to pay=Initial estimate+Incentive+70% of overage =$5000+$1000+$700=$6700

26 B

Explanation: 
Overage=20% of $5000=$1000
Agreement between buyer and seller was to share the departure from original estimate at a pre-determined rate of 70 (buyer)/30 (seller).
30% of overage=$300 which seller has to bear.

166 C
Explanation: The time taken for each of the paths is as follows:
ABCDE?5d+5d+2d+1d=13d
AFGCDE?2d+3d+1d+2d+1d=9d
AHIDE?4d+6d+3d+1d=14d
Since AHIDE is the path with the longest duration, it is the critical path for this project.

167 A
Explanation: The time taken for each of the paths is as follows:
ABCDE?5d+5d+2d+1d=13d
AFGCDE?2d+3d+1d+2d+1d=9d
AHIDE?3d+6d+3d+1d=13d
Since AHIDE and ABCDE take the same time to complete and are the longest paths, they are the critical paths for this project.

Explanation: Both activities B and C have to be completed before activity D can start. Activity C ends on Mar 8 (EF). Activity B ends on Mar 9 (EF). Since the latest EF is Mar 9, D can start only on Mar 10.

170 A
Explanation: The duration of activity A is 4 days. If activity A starts on Mar 3, it will finish by end of day, Mar 6. Hence EF date is Mar 6.
