Q: Five houses in a row — which house is in the middle? (variant) Houses A, B, C, D, O in a line. A is to the right of B and to the left of C (B < A < C). O is on the right side of A. B is to the right of D. Which house is in the middle?

Introduction / Context: This is equivalent in structure to the earlier five-house problem; we again seek the middle slot. Given Data / Assumptions: B 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 1

Five houses in a row — which house is in the middle? (variant) Houses A, B, C, D, O in a line. A is to the right of B and to the left of C (B < A < C). O is on the right side of A. B is to the right of D. Which house is in the middle?

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
