­The table shows a marketing director's to-do list at the end of the

­In the table mentally calculate how many days left and their corresponsing deadline like:
Assemble sales teams (AST) 1 day 3-November
Create marketing presentations (CMP) 2 days 12-November

Mark the Days along with the deadlines

1 2 3 4 5 6 7 8 9 10 11 12

If s/he does AST on 3rd , s/he will still be able to complete WPS by 5 ( using 4 days among 1 2 4 5 ) and additional 2 days after that can be used to finish DPS by 8.

If s/he does CMP on 3rd , s/he has to complete AST on one of 1 or 2. But if s/he does that s/he won't have 4 days remaining to complete WPS by 5.

If s/he does WPS on 3rd she can still manage the other tasks by deadline ( check this out by yourself )

I believe this question says that the director has to work continously to get a task done. It can not start the task on one day and have some gaps (gap days) and then continue back.
eg : if a task starts on 3rd, and needs 4 days to complete , then 3/4/5/6 all days the director must continue on the same task. He cannot start (say task A) on 3rd and pick another task(say B) on 4th day, continue to work on B for say 4 days and then resume A.
Is this understanding correct ?­

the key is more urgent tasks should be addressed first.

I think this question is more focused on the bolded words For each of the following tasks, select Yes if the information provided allows that the director could work on that task on November 3 and still meet the deadlines for all four tasks.

So, it means that on Nov 3rd, Directly will work on the task in question.
So,
Working on AST on 3rd - yes, as it has only 1 day of task remaining and if M works on that on Nov 3rd, s/he can complete WPR by working on 1st, 2nd 4th and 5th (as it required 4 days worth work left.)
DPS can be completed by working on 6th and 8th (7th is no work day) and CMP can be taken on any 2 of the remaining days.

If M takes CMP on 3rd. Then, M can work on AST anywhere on 1st and 2nd(let's say 1st for out clarity). Now comes the interesting part WPR required 4 days to complete, but M has only 3 days 2nd, 4th and 5th. So, not possible

Similarly if M takes WPR on 3rd then M can work on AST anywhere on 1st and 2nd(let's say 1st for out clarity).
WPR will be worked on 2nd, 3rd, 4th, 5th. DPS can be completed by working on 6th and 8th (7th is no work day) and CMP can be taken on any 2 of the remaining days.

Although your answer is right, remember that the director can not work on Nov 7. so it will be good to remove that day from the timeline/dateline for plotting the answers.

Hi KarishmaB, can you pls explain why we should take that the director will work on one task till it is completed and then take up another task. why cannot it be like work on task1 for 2 days then work on task2 for 2 days and then come back to task1?

The director can work on only one task in one day.
As you said, the Director can definitely "work on task1 for 2 days then work on task2 for 2 days and then come back to task1" or any other task as long as the Task is finished before the deadline (constraints for answering the question)
The answers to this question won't change because the director has deadlines for finishing the tasks.
