Concepts
Question 1
Given: A, P, R, X, S, and Z are sitting in a row. S and Z are in the center. A and P are at the ends. R is sitting to the left of A. Find who is to the right of P.
Step-by-Step Reasoning
- We have 6 persons: A, P, R, X, S, and Z.
- S and Z are in the center → positions 3 and 4 in a row of 6.
- A and P are at the ends → A and P occupy positions 1 and 6.
- R is sitting to the left of A. If A were at position 1 (left end), R cannot be to the left of A (no space on the left end). So A must be at position 6 (right end) and P at position 1 (left end).
- Now we have: P (1), ? (2), S (3), Z (4), ? (5), A (6). Since R must be to the left of A, R can be at position 5, and the remaining person X at position 2.
- Final arrangement: P(1), X(2), S(3), Z(4), R(5), A(6).
- To the right of P (position 1) is X (position 2).
Answer
The person to the right of P is X.
Question 2
Given: A, B, C, D, and E are sitting on a bench. Conditions:
- A sits next to B.
- C sits next to D.
- D not sitting with E who is on the left end.
- C is second from the right.
- A is to the right of B and E.
- A and C are sitting together.
Find in which position A is sitting:
Options:
- Between B and D
- Between B and C
- Between E and D
- Between C and E
Step-by-Step Reasoning
- Place E at the left end → E(1).
- C is second from the right → in a row of 5, C is at position 4.
- D not with E → D not at position 2. C at 4 means D at 3 or 5. But A and C sit together. If C(4), A is either (3) or (5).
- A is to the right of B and E, and A sits next to B. With E at (1), put B at (2), A at (3), C at (4), D at (5). Check conditions: A between B(2) and C(4) correct, D(5) not next to E(1), all conditions hold.
Answer
A is sitting between B and C.
Question 3
This is a rephrased version of question 2. The answer remains the same after verification.
Answer
A is sitting between B and C.
Question 4
Given: A,B,C,D,E,F,G facing north in a row with conditions:
- F is directly to the right of E.
- E is the fourth letter to the right of G.
- C is the neighbor of B and D.
- The third person to D’s left is at one of the ends.
Find:
- A’s position
- B’s immediate neighbors
- Which statement is false
Step-by-Step Reasoning
- Place G at position 1 (left end) for convenience, then E is fourth to the right: E at position 5, F right of E: F at 6.
- Seven in a row: G(1), ?(2), ?(3), D(4), E(5), F(6), A(7). D at 4 chosen so that 3rd to D’s left is G at 1.
- C neighbors B and D: C at 3, B at 2, leaving A at 7.
- Final: G(1), B(2), C(3), D(4), E(5), F(6), A(7).
A’s position: A is at extreme right end.
B’s neighbors: B(2), neighbors: G(1) and C(3) → C and G are B’s neighbors.
False statement: The one suggesting B is at an end is false. (Any statement claiming B is at an endpoint is false.)
Answers
A is at the extreme right.
B’s immediate neighbors are C and G.
The false statement is the one indicating an endpoint as B’s position.
Question 5
Given two parallel lines: Five men (A,B,C,D,E) facing south and five ladies (M,N,O,P,Q) facing north.
- Q opposite B, B just to the left of D.
- C and N diagonally placed.
- E opposite O, O is on M’s right.
- P, left of Q, opposite side of D.
- M at one end.
This leads to a complex arrangement. The final stable arrangement after deductions (one possible correct arrangement) is:
Men (facing south): A(1), E(2), C(3), B(4), D(5)
Ladies (facing north): M(1), O(2), P(3), Q(4), N(5)
We will use this arrangement for subsequent questions.
Question 6
After switching places: O↔P, A↔E, B↔Q, we need to find who is second to the right of the person opposite to the second to the right of P.
Step-by-Step Reasoning
1. Original ladies: M(1), O(2), P(3), Q(4), N(5)
Swap O and P: M(1), P(2), O(3), Q(4), N(5).
Original men: A(1), E(2), C(3), B(4), D(5)
Swap A and E: E(1), A(2), C(3), B(4), D(5)
Swap B and Q: Men: E(1), A(2), C(3), Q(4), D(5); Ladies: M(1), P(2), O(3), B(4), N(5).
Second to right of P (ladies face north, so right means to their own right side): P(2) → right positions: O(3) is first right, B(4) second right.
Opposite B(4-ladies) is Q(4-men).
Men face south, their right is reversed. From Q(4-men) to his right: counting right as per facing south means one seat lower number each step: Q(4) first right C(3), second right A(2).
Answer
The final answer is A.
Question 7
After B takes place of E, E takes place of Q, Q takes place of B, who will be the second to the left of the person opposite to O?
Step-by-Step Reasoning
Original men: A(1), E(2), C(3), B(4), D(5)
Swap B and E: A(1), B(2), C(3), E(4), D(5)
Swap E and Q (Q at ladies(4)): Men: A(1), B(2), C(3), Q(4), D(5); Ladies: M(1), O(2), P(3), E(4), N(5)
Swap Q and B in men line: A(1), Q(2), C(3), B(4), D(5)
Ladies remain: M(1), O(2), P(3), E(4), N(5)
O opposite Q(2). We need second to the left of Q. Facing south, left means increasing position: Q(2)-left: C(3) first left, B(4) second left.
Answer
B
Question 8
Seven cars facing East: Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford, Fargo
- Cadillac next right of Fargo.
- Fargo is fourth to right of Fiat.
- Maruti between Ambassador and Bedford.
- Fiat at one end, 3rd to left of Ambassador.
Step-by-Step Reasoning
1. Place Fiat at left end (position 1). Ambassador at position 4 (since Fiat is 3 left of Ambassador).
Positions: Fiat(1), Bedford(2), Maruti(3), Ambassador(4), Fargo(5), Cadillac(6), Mercedes(7).
- Cars on both sides of Cadillac(6): Fargo(5) and Mercedes(7).
- Which statement correct? "Maruti is next left of Ambassador" is correct.
- Correct statement: "Cadillac is next left to Mercedes."
- To right of Ambassador(4): Fargo(5), Cadillac(6), Mercedes(7) → matches "Mercedes, Cadillac and Fargo".
- Position of Mercedes? Fourth to the right of Maruti or at position 7 from Maruti(3) count 4 steps right: 4(Amb),5(Far),6(Cad),7(Mer). Yes, correct.
Answers
Fargo and Mercedes
Maruti is next left of Ambassador
Cadillac is next left to Mercedes
Mercedes, Cadillac and Fargo
Mercedes is fourth to the right of Maruti
