Eight persons A, B, C, D, E, F, G and H sit around a square-shaped table. Four persons sit at the corners and face inside, while the other four sit at the middle of each side and face outside.
Each person is from a different city: Delhi, Mumbai, Kolkata, Chennai, Pune, Jaipur, Hyderabad and Bengaluru.
G sits two places away from the one who is from Pune. The one who sits immediate left of the one who is from Pune does not sit at the middle of a side. The one from Delhi sits third to the right of G.
One person sits between the ones from Delhi and Chennai. A sits immediate right of the one from Chennai. D sits third to the left of A, and E is adjacent to D.
C is from Jaipur and sits immediately to the right of B. B does not sit at a corner. Three persons sit between the ones from Kolkata and Mumbai. The ones from Mumbai and Delhi are not immediate neighbours. B and D are not from Bengaluru. F does not sit immediate right of A.

Show answer & explanation
Correct answer: D
Concept
In a square-table arrangement, corner seats face inward and side-middle seats face outward. Left and right therefore reverse between the two seat types.
Fix one side seat to remove rotational duplicates. Then build linked constraints as a chain and test the few remaining cases instead of guessing a complete arrangement.
Application
Fix B at side-middle seat 2. B faces outward, so C, immediately to B’s right, is at corner seat 3. C’s city is Jaipur.
For each possible seat of G, place Delhi three seats to G’s right. Next place Chennai two seats from Delhi, put A immediately to Chennai’s right, put D three seats to A’s left, place E adjacent to D, and enforce that F is not immediately right of A.
The case table leaves only G at seat 4. It then fixes Delhi at seat 7, Chennai at seat 1, A at seat 8, D at seat 5, E at seat 6, F at seat 7, and H at seat 1.
G at seat 4 is two places from seats 2 and 6, so Pune could initially be at B’s seat 2 or E’s seat 6. In either case, Pune’s immediate-left neighbour is at a corner, so the left-neighbour clue alone does not decide between them.
Kolkata and Mumbai must be opposite. The pairs 1–5, 2–6, and 3–7 already contain Chennai, Pune, Jaipur, or Delhi, so the Kolkata–Mumbai pair is seats 4–8. Seat 8 is adjacent to Delhi at seat 7, so it cannot be Mumbai; therefore G is from Mumbai and A is from Kolkata.
If E at seat 6 were from Pune, the only unassigned cities for B and D would be Hyderabad and Bengaluru. That is impossible because both B and D are stated not to be from Bengaluru. Therefore B is from Pune.
The only cities left for D and E are Hyderabad and Bengaluru. Since D is not from Bengaluru, D is from Hyderabad and E is from Bengaluru.
G-seat case check
G seat | Result of linked clues |
|---|---|
1 | The two Pune candidates are C’s Jaipur seat or a seat whose immediate-left neighbour is side-middle. |
4 | All linked clues fit; this is the surviving case. |
5 | The two Pune candidates are C’s Jaipur seat or a seat whose immediate-left neighbour is side-middle. |
6 | The Chennai–A relation collides with C or places A at G’s seat. |
7 | The Chennai–A relation places A at C’s or G’s seat. |
8 | Delhi would occupy C’s Jaipur seat. |
Completed arrangement
Clockwise seat | Person | City |
|---|---|---|
1 | H | Chennai |
2 | B | Pune |
3 | C | Jaipur |
4 | G | Mumbai |
5 | D | Hyderabad |
6 | E | Bengaluru |
7 | F | Delhi |
8 | A | Kolkata |
Cross-check
Delhi at F is third to G’s right, and Chennai at H has one person between it and Delhi.
Mumbai at G is opposite Kolkata at A, and Mumbai is not adjacent to Delhi.
B and D are Pune and Hyderabad, so neither is from Bengaluru.
Therefore, E is from Bengaluru.
