Answer:
The question asks you to select two dates, the start and finish dates of Marketing’s team training session.
Let’s break down the statements, step by step:
First, integrate statements that refer to one another and create a list:
Product should be scheduled after HR: HR->Product
Data is before or after Product: Data-> Product or Product->Data.
Since you know HR has to be the team that immediately precedes Product, then the correct order would be Product->Data
Taken together, so far we have: HR->Product->Data – these teams should be scheduled immediately one after the other.
Second, organize possible lists:
The other two departments that are not scheduled yet are Marketing and Software development. According to Software Development’s statement, these two departments can’t be scheduled one after the other. Therefore, they will be in the first and last spots of the line.
The options are:
Marketing-> HR->Product->Data->Software Development
Or
Software Development-> HR->Product->Data >Marketing
Marketing is not available on the 5th though, meaning they can’t be first in line.
As a result, Marketing will be the last team to do their training.
Third, choose the correct time frame
Counting every 4 consecutive weekdays, there are 5 slots:
(1) 1,4,5,6
(2) 7,8,11,12
(3) 13,14,15,18
(4) 19,20,21,22
(5) 25,26,27,28.
The last training session will be scheduled between the 25th and 28th, so these would be the first and last training days of the Marketing team.
