Accepted Answer

Introduction / Context:This is equivalent in structure to the earlier five-house problem; we again seek the middle slot.Given Data / Assumptions:B < A < C; O > A; B > D.Concept / Approach:Construct a valid order (e.g., D, B, A, O, C) and check all relations.Step-by-Step Solution:In D–B–A–O–C, A occupies position 3 (middle), satisfying all constraints.Final Answer:A

Question 2

Six friends in a row facing East — who is at the left end? Friends A, B, C, D, E, F face East in one row. C is between A and E. B is just to the right of E and left of D (… E, B, D … contiguous E–B). F is not at the right end. Who is at the left end?

Accepted Answer

Introduction / Context:We must place six people with one adjacency (E–B) and a “between” constraint, then identify the leftmost person.Given Data / Assumptions:E immediately left of B; B left of D.C between A and E (order A … C … E).F not at the right end.Facing East informs only ends; left-to-right order is as viewed.Concept / Approach:Anchor the E–B block and fit A … C … E to its left to satisfy “C between A and E.”Step-by-Step Solution:Place E=3, B=4 (middle block).Then A … C … E must use positions 1–2–3 as A=1, C=2, E=3.Remaining D and F take 5 and 6, with B left of D ⇒ D=6, F=5 (also keeps F off the right end).Row: 1 A, 2 C, 3 E, 4 B, 5 F, 6 D ⇒ left end is A.Verification / Alternative check:Other placements of the E–B block that satisfy “A … C … E” still force A to the extreme left.Why Other Options Are Wrong:F/C/B cannot be at position 1 in any valid arrangement meeting all clues.Final Answer:A

Question 3

Row facing South — who sits at the extreme right end? Five friends face South. Mohan is between Balu and Raju. Raju is to the immediate right of Praveen. Amith is to the right of Balu. Who occupies the extreme right end of the row (as viewed)?

Accepted Answer

Introduction / Context:Facing South reverses individual left/right relationships relative to our left-to-right view. We must still report the extreme right end as seen by the observer.Given Data / Assumptions:“Raju is to the immediate right of Praveen.” Facing South ⇒ in our left→right drawing, Raju sits immediately left of Praveen.“Mohan is between Balu and Raju.” So either Balu – Mohan – Raju or Raju – Mohan – Balu (in our left→right order).“Amith is to the right of Balu” (our left→right sense).Concept / Approach:Place the adjacent pair (Raju, Praveen) as Raju–Praveen. Fit Mohan between Balu and Raju. Then push Amith to the right of Balu and locate the rightmost slot.Step-by-Step Solution:One valid arrangement (left→right): Raju, Praveen, Balu, Mohan, Amith.Checks: Raju immediately left of Praveen ✔ (i.e., right of Praveen when facing South); Mohan between Balu and Raju ✔; Amith right of Balu ✔.Hence the extreme right position is occupied by Amith.Verification / Alternative check:Any equivalent re-placement that honors the clues still yields Amith at the rightmost end.Why Other Options Are Wrong:Balu/Praveen/Mohan are interior under these constraints and cannot be the extreme rightmost.Final Answer:Amith

Question 4

Circle (facing centre) — who is to Pappu's left? Six girls sit in a circle facing the centre. Subbu is to the left of Pappu. Revathi is between Subbu and Nisha. Aruna is between Pappu and Keerthana. Who sits to the left of Pappu?

Accepted Answer

Introduction / Context:In circular seating with everyone facing the centre, a person’s left neighbor is the immediate clockwise neighbor.Given Data / Assumptions:“Subbu is to the left of Pappu” ⇒ Subbu is Pappu’s immediate clockwise neighbor.“Revathi is between Subbu and Nisha.”“Aruna is between Pappu and Keerthana.”Concept / Approach:Once “left of Pappu” is explicitly stated as Subbu, the query is answered directly; the remaining clues ensure a consistent full circle exists.Step-by-Step Solution:Identify Pappu. Place Subbu to Pappu’s immediate left (clockwise).Arrange the remaining four so that Revathi falls between Subbu and Nisha on one arc and Aruna between Pappu and Keerthana on the other arc; such an arrangement is feasible and does not affect who sits immediately left of Pappu.Verification / Alternative check:Construct any concrete clockwise order satisfying both “between” constraints (e.g., Pappu–Subbu–Revathi–Nisha–… and Pappu–…–Aruna–Keerthana–…), confirming Subbu’s position remains Pappu’s left neighbor.Why Other Options Are Wrong:They contradict the explicit statement “Subbu is to the left of Pappu.”Final Answer:Subbu

Accepted Answer

Concept & Logical Deduction: Linear seating arrangements with unknown totals require establishing a fixed starting point or sequence formula. Here, combining distance constraints and the odd/even position rules (Odd = Manager, Even = Associate) locks in the exact positions. Step-by-Step Solution: Let's decode the entire seating arrangement step-by-step: 1. Initial Placements: S is the extreme left Manager, so S is at Position 1. 2. Finding Q & R: J sits 3rd to the right of R. P is the 3rd Associate to the right of J. Since J is at an odd position (Manager), the 3rd Associate to the right is 5 positions away (+1, +3, +5). Thus, P = J + 5. 3. Calculating Q: The gap between J and P is 4 persons ((J+5) - J - 1 = 4). The puzzle states the gap between Q and S is 1 more than the gap between J and P. Thus, Q to S gap = 5. Since S is at 1, Q must be at 7. 4. Linking Q, R, and J: 2 persons sit between Q(7) and R. So R = 4 or 10. J is 3rd to right of R (R+3). If R=4, J=7 (clashes with Q). So R = 10, J = 13, and P = 18. 5. Finding T & X: 4 persons sit between Q(7) and T. Since T is not right of R(10), T = 2. There are 3 Managers (odd positions) between T(2) and X. These managers are at positions 3, 5, and 7. Thus, X is placed immediately after 7, at position 8. 6. Finding G: 5 persons sit between J(13) and G. G can be 7 (clashes with Q) or 19. So G = 19. 7. Total Persons: Gap between Q(7) and R(10) is 2. This is 1 more than persons right of G(19). So 1 person is to the right of 19. Total persons = 20. 8. Placing Z & U: Gap between R(10) and G(19) is 8. Gap between X(8) and Z is 8, so Z = 17. U is to the right of Z and P, occupying the final position 20. 9. Final Sequence (1 to 20): S(1), T(2), M(3), A(4), M(5), A(6), Q(7), X(8), M(9), R(10), M(11), A(12), J(13), A(14), M(15), A(16), Z(17), P(18), G(19), U(20). Answering the specific question: • 3rd Associate to the right of J(13) is P at position 18. • 4th Manager from the extreme right (20). Managers are odd: 19(G), 17(Z), 15, 13(J). The 4th is J at position 13. • Persons between 13 and 18 = 18 - 13 - 1 = 4. Exam Strategy & Shortcut: Always fully map an uncertain linear arrangement once if multiple questions follow it. Use algebraic representation (x, x+3, x+5) to find gaps quickly instead of drawing massive tick-mark diagrams that are prone to counting errors. Common Pitfall: Miscounting "persons between". The number of persons strictly *between* position A and position B is always |A - B| - 1. Final Answer: Therefore, the correct answer is 4.

Concept & Logical Deduction: Linear seating puzzles with distance constraints rely heavily on establishing coordinate positions. Finding the "middle" requires averaging the position indices of the two target individuals. Step-by-Step Solution: From the decoded seating arrangement (Total 20 persons): • Positions are strictly mapped from left to right (1 to 20). • S(1), T(2), Q(7), X(8), R(10), J(13), Z(17), P(18), G(19), U(20). • Identify Target 1: The person R is located at position 10. • Identify Target 2: Z is located at position 17. The person sitting immediately to the left of Z is at position 17 - 1 = 16. • Find the Midpoint: To find the exact middle of positions 10 and 16, calculate the average: Midpoint = (10 + 16/2) = (26/2) = 13 • Look up position 13 in the master arrangement. The person sitting at position 13 is J. Exam Strategy & Shortcut: If you know the positions mathematically, never count manually on your fingers or on a drawn line. Just average the two indices. If the result is a fraction (e.g., 13.5), it means there is no single middle person. Here, 13 is an integer, making J the clear answer. Common Pitfall: Accidentally finding the middle between R(10) and Z(17) instead of the person *immediately to the left* of Z. (10+17)/2 = 13.5, which would incorrectly lead you to select "Unknown person" or "None". Always read the relational descriptors carefully. Final Answer: Therefore, the correct answer is J.

Concept & Logical Deduction: Evaluating statements in complex seating arrangements requires checking each option against your firmly established position sequence. Step-by-Step Solution: Let's evaluate each option using our decoded 20-person linear arrangement: • Master Sequence Snapshot: S(1), T(2), Q(7), X(8), R(10), J(13), Z(17), P(18), G(19), U(20). • Option A: Number of persons right of Z(17) is 3 (positions 18, 19, 20). Persons between Q(7) and R(10) is 2. Since 3 
eq 2, this is FALSE. • Option B: T is at position 2, X is at 8. T is to the *left* of X, not right. FALSE. • Option C: S is at position 1, J is at 13. S is to the extreme *left* of the row, so it cannot be right of J. FALSE. • Option D: Check the number of Managers (odd positions) strictly between X(8) and P(18). The odd positions between 8 and 18 are: 9, 11, 13(J), 15, and 17(Z). There are exactly 5 Managers between them. Since 5 is strictly "more than two", this statement is TRUE. • Option E: The person seated 5th to the right of Q(7) would be at position 7 + 5 = 12. P is seated at position 18. FALSE. Exam Strategy & Shortcut: When checking positional statements, only evaluate what is strictly necessary. For Option D, noting that X is 8 and P is 18 means the gap is 9 people. In any sequence of 9 alternating people, there will be at least 4 odd positions (Managers). This instantly confirms it is more than two without even identifying them perfectly. Common Pitfall: Skimming over relational words. Misreading "Managers sitting between" as "Total persons sitting between" can cause hesitation, though both would technically be more than two in this specific case. Precision is key. Final Answer: Therefore, the correct answer is The number of Managers sitting between X and P is more than two.

Accepted Answer

Concept & Logical Deduction: This question tests relative positional referencing. You must first find the anchor person based on a condition ("5th Manager from the left end"), move relative to that person, and then calculate the final position relative to a second anchor (Q). Step-by-Step Solution: From the deduced arrangement: • Total row has 20 positions. Managers sit exclusively at odd-numbered positions. • Let's identify the Managers from the extreme left (Position 1): - 1st Manager = Position 1 (S) - 2nd Manager = Position 3 - 3rd Manager = Position 5 - 4th Manager = Position 7 (Q) - 5th Manager = Position 9 • The question asks for the person who sits third to the left of this 5th Manager (Position 9). • Calculate this position: 9 - 3 = 6. The target person is seated at position 6. • Now, we must find the position of the person at Position 6 with respect to Q. • Q is seated at position 7. • Position 6 is exactly one spot before position 7. • Therefore, the person at position 6 sits to the immediate left of Q. Exam Strategy & Shortcut: Because Managers strictly occupy odd positions, the n-th manager from the start (where position 1 is a manager) is simply 2n - 1. The 5th manager is 2(5) - 1 = 9. Third left is 9 - 3 = 6. Since Q is explicitly the 4th manager (2(4) - 1 = 7), position 6 is naturally the immediate left of position 7. Common Pitfall: Confusing absolute and relative positions. Do not calculate "third to the left of Q" when it asks for the position *with respect to* Q. Read the sentence structure backward to ensure you evaluate dependencies in the correct order. Final Answer: Therefore, the correct answer is Immediate left.
