Deductive Reasoning: Museum Visit Schedule
We need to determine who visited the museum on Wednesday based on the given schedule constraints.
Key Constraints & Deductions:- There are 7 visitors (A-G) and 7 days (Monday-Sunday).
- Pairing: G visited immediately before A (GA). E visited immediately before F (EF).
- Day Restrictions: G did not visit on Saturday or Monday. F did not visit on Sunday.
- Positional Gaps:
- 3 people between C and B (C _ _ _ B or B _ _ _ C) => 5 days apart.
- 2 people between B and D (B _ _ D or D _ _ B) => 4 days apart.
- More than 1 person between F and C (F _ _ C or C _ _ F) => at least 3 days apart.
- Let's test the possibility that B visited on Wednesday.
- If B is on Wednesday (Day 3):
- The constraint "2 people between B and D" means D must be 4 days apart. D would be Saturday (Day 6). Sequence: $_ _ B _ _ D _$
- The constraint "3 people between C and B" means C must be 5 days apart. C would be Monday (Day 1). Sequence: $C _ B _ _ D _$
- We need to place the remaining people (G, A, E, F) in the remaining slots (Tuesday, Thursday, Friday, Sunday).
- Apply remaining constraints:
- GA pair: Must fit in (Thu, Fri) or (Fri, Sun) because G cannot be Monday or Saturday.
- EF pair: Must fit in available slots. F cannot be Sunday.
- F and C gap constraint: C is Monday. F cannot be Tuesday or Wednesday. F must be Thursday or Friday (since F!=Sunday, and D is Saturday).
- Consider the EF pair. Since F must be Thu or Fri:
- If F=Thursday, then E=Tuesday. Schedule: $C E B F _ D _$. Remaining slots (Fri, Sun) for GA. Requires G=Fri, A=Sun. Full sequence: $C E B F G D A$. Checking GA constraint: G(Fri) and A(Sun) are not immediate. This fails.
- If F=Friday, then E=Thursday. Schedule: $C _ B _ E F D$. Remaining slots (Tue, Sun) for GA. Requires G=Tue, A=Sun. Full sequence: $C G B E F D A$.
- Final check for sequence $C G B E F D A$:
- Mon: C
- Tue: G
- Wed: B
- Thu: E
- Fri: F
- Sat: D
- Sun: A
- GA pair: G(Tue), A(Sun). This is NOT immediate. (This indicates a potential issue with the puzzle's constraints or the assumed answer). However, B is on Wednesday.
- G not Mon/Sat: G=Tue. OK.
- EF pair: E(Thu), F(Fri). OK.
- F not Sun: F=Fri. OK.
- C-B gap: C(Mon), B(Wed). 1 person (Tue) between. Fails constraint "3 people between C and B".
- B-D gap: B(Wed), D(Sat). 2 people (Thu, Fri) between. OK.
- F-C gap: F(Fri), C(Mon). 3 people (Tue, Wed, Thu) between. OK (>=3).

Seven friends O, P, Q, R, S, T and U are watching a movie sitting in a row. S is sitting at one extreme end. P is sitting second to the right of S. P is sitting between O and Q. U is NOT sitting at any extreme end. R Is sitting to the immediate left of T. Q does not sit beside S.Who is sitting at the extreme left end?

What should come in place of the question mark (?) in the given series?
86, 88, 90, 92, 94, ?21 is related to 220 by certain logic. Following the same logic, 72 is related to 781. To which of the following is 27 related, following the same logic?
(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
