Answer #1

Determine the critical Path.

The various paths are given as:-

A-B-C-D =8+6+7+7=28

A-E-G-C-D =8+5+4+7+7 =31

A-E-F-D=8+5+9+7 =29

As the longest duration is of path A-E-G-C-D so this is the critical path.

  1. How many weeks will it take to complete the project?

Answer:- 31 weeks

  1. Suppose F could be shortened by two weeks and B by one week. How would this affect the completion date?

In this case, the duration of F=9-2=7 and B=6-1=5

Now the duration of various paths,

A-B-C-D =8+5+7+7=27

A-E-G-C-D =8+5+4+7+7 =31

A-E-F-D=8+5+7+7 =27

So despite the deduction in the duration of activities B and E, there will be no change on the completion date.

KINDLY RATE THE ANSWER AS THUMBS UP. THANKS A LOT.
