Month-Date Scheduling | Worksheet 5/10 - Intermediate expert challe...

Question 1

Eight people attend seminars in four different months (January, March, May, July) on two dates (5th and 15th). Two people attend per month. The constraints are: - R attends in March - U attends on the 15th - Exactly two people attend between T and Q - S attends in the same month as V In which month does T attend?

Step-by-step solution:

Timeline Grid Method:
1. Create month-date grid:
Jan 5 | Jan 15 | Mar 5 | Mar 15 | May 5 | May 15 | Jul 5 | Jul 15

2. Apply constraints:

- U on 15th (any month, date 15)
- Two people between T and Q
(If T at position 1, Q at position 4)
- S and V in same month

3. Systematic placement:
- Place R at Mar 5 (satisfies March constraint)
- Place U at Mar 15 (satisfies 15th constraint)
- For 'two between' constraint: If T at Jan 5, Q at Mar 15
- S and V together: May 5 & May 15

4. Verification:
