Each of P, Q, R, S, T, U and V has an exam on a different day of a week starting from Monday and ending on Sunday of the same week. T has the exam on Tuesday. Only two people have exams between R and T. P has the exam immediately after S but not on Sunday. Q has the exam before V but not on Monday. How many people have exams between U and P?
Solution: Number of people between U and P
Step 1: Days of the week
Monday (1) to Sunday (7)
Step 2: Given conditions
- T is on Tuesday → T = 2
- Only two people between R and T → R = 5 (Friday)
- P is immediately after S
- P is not on Sunday
- Q is before V and Q is not on Monday
Step 3: Arrange P and S
Possible consecutive pairs: (3,4) and (6,7)
But P is not on Sunday → so (6,7) is not possible
So:
S = 3 (Wednesday)
P = 4 (Thursday)
Step 4: Remaining arrangement
- U = 1 (Monday)
- Q = 6 (Saturday)
- V = 7 (Sunday)
Final Arrangement
| Day | Person |
|---|---|
| Monday | U |
| Tuesday | T |
| Wednesday | S |
| Thursday | P |
| Friday | R |
| Saturday | Q |
| Sunday | V |
Step 5: Final Answer
U = Monday (1) and P = Thursday (4)
People between them: T (2) and S (3)
Answer: two
