Q selected Wednesday. R said that he will select the day immediately before P. S decided to select any available day between P's and Q's selection. T selected Sunday. U said that he will select the day immediately before Q. Which day is left for V to select?

• A. Thursday
• B. Tuesday
• C. Wednesday
• D. Monday

Answer 1

Answer:

D. Monday

The day left for V to select is Monday.

We can determine the schedule from Sunday to Saturday by placing each person based on the given clues:

Day of the Week	Person Selected	Clue/Reasoning
Sunday	T	Given directly in the question.
Monday	V	Remaining day for the last person.
Tuesday	U	Immediately before Q (Wednesday).
Wednesday	Q	Given directly in the question.
Thursday	S	The only remaining available day between Q and P.
Friday	R	Immediately before P (Saturday).
Saturday	P	Given directly in the question.

1. Direct Placements:

   • T selects Sunday.

   • Q selects Wednesday.

   • P selects Saturday.

2. Immediate Days:

   • R chooses the day immediately before P, which means R selects Friday.

   • U chooses the day immediately before Q, which means U selects Tuesday.

3. Between Selections:

   • S chooses an available day between Q (Wednesday) and P (Saturday). The remaining open days in that range are Thursday and Friday. Since Friday is already taken by R, S must select Thursday.

4. Conclusion:

   • Looking at the entire week, Sunday, Tuesday, Wednesday, Thursday, Friday, and Saturday are all occupied.

   • Therefore, Monday is the only day left for V to select.

V is left with Monday.
