Question

Consider the following table of activities A through E in which A is the start node and E is the stop node. Assume the project starts on Monday, May 4, 2020 and no work is done on weekends (Saturday and Sunday).

Activity	Duration (days)	Predecessor
A	5	--
B	5	A
C	10	A
D	4	A
E	5	B, C, D

On a piece of scratch paper, draw the Gantt Chart for the table above. What is the late start date for activity E?

• Monday, May 18, 2020

• Tuesday, May 19, 2020

• Friday, May 22, 2020

• Tuesday, May 26, 2020

• Monday, May 25, 2020

Answer 1

Gantt chart is as below:

Activities B, C and D are dependent on A. So, as soon as A gets completed, all three gets started.

Activity E is dependent on B, C and D so it will start as soon as all three gets completed. The longest duration is of B so E will start after B is completed

E starts on 25th May Monday

Ans - Monday, May 25, 2020
