How many people have exams between Q and U?
Schedule Constraints Analysis
We need to arrange 7 people (P, Q, R, S, T, U, V) for exams on 7 different days, from Monday to Sunday.
- 4 people after V: This constraint means V's exam must be on Wednesday. Only Thursday, Friday, Saturday, and Sunday are after Wednesday, accounting for 4 days.
- 4 people before S: This implies S's exam must be on Friday. Monday, Tuesday, Wednesday, and Thursday precede Friday, totaling 4 days.
Current Schedule Snapshot:
Monday: ?, Tuesday: ?, Wednesday: V, Thursday: ?, Friday: S, Saturday: ?, Sunday: ?
Determine Exam Order
P after R but before V: The condition is \( R < P < V \). Since V is on Wednesday, R and P must take the earlier available slots. R must be on Monday and P on Tuesday to satisfy this order.
Updated Schedule: Monday: R, Tuesday: P, Wednesday: V, Thursday: ?, Friday: S, Saturday: ?, Sunday: ?
T after Q, not on Sunday: The remaining people are Q, T, and U. The available days are Thursday, Saturday, and Sunday.
- T's exam cannot be on Sunday.
- Q's exam must occur before T's exam.
- Given the available days (Thursday, Saturday, Sunday), Q must take Thursday, and T must take Saturday.
- This leaves Sunday for the last person, U.
Final Exam Order:
- Monday: R
- Tuesday: P
- Wednesday: V
- Thursday: Q
- Friday: S
- Saturday: T
- Sunday: U

Q's exam is scheduled for Thursday.
U's exam is scheduled for Sunday.
The exams occurring between Thursday and Sunday are on Friday (S) and Saturday (T).
