Direction : Read the following information carefully and answer the questions given below:
Some students attend the lectures and they all are arranged in three parallel rows such that row1 is north of row2 and row 3 is south of row 2. Each row has 8 seats. All the students face north direction. Some seats are vacant in each row. Twelve students- Allen, Fame, Emma, Alpha, Coco, Nick, Ivory, London, Olive, Unique, Jack and Den who attend the lectures are divided into two classes i.e., class A and class B. The students whose name start with a vowel belongs to class A and the rest belong to class B. The students in class A are sitting in the alternative seats from the second seat of Row 1 when counts from the left end according to the dictionary order followed by class B students who are sitting in reverse alphabetical order. After row 1, students are sitting in row 2 then in row 3 following the same rule. All students are sitting in the alternative seats only. Now the students sit around two circular tables i.e., Table1 and Table2 and all are facing the centre. Students belong to Class A sit in table 1and the rest of them sit in table 2. Conditions for table 1: Allen sits opposite to the one who sits second from the left end in row 2. The one who sits right of olive in row 2 sits second to the right of Allen. Alpha doesn’t sit adjacent to Olive and sit opposite to Emma.
Conditions for table 2: London sits second to the right of the one who sits adjacent to Unique. The one who sits at extreme end sit third to the left of London. Jack sits opposite to Den and doesn’t sit adjacent to Nick.
Who among the following sits opposite to Coco in circular arrangement?
- A.
Fame
- B.
The one who sits adjacent to Nick
- C.
The one who sits at extreme end in row 2
- D.
Either Fame or the one who sits adjacent to Nick
- E.
None of these
Show answer & explanation
Correct answer: C
Concept: In a combined linear-row-plus-circular-table puzzle, first fix the two groups using the stated rule (here: names starting with a vowel vs. a consonant), then seat each group in the stated linear order so a person can be identified by their row position whenever a later circular condition needs a row-based anchor. In a circular arrangement of n people facing the centre, moving k seats to the right is the same seat as moving (n minus k) seats to the left, and moving exactly n/2 seats in either direction always lands on the person seated diametrically opposite -- both facts are used below. In this puzzle, some row seats are vacant, so a phrase like "adjacent to X" or "the one to the right of X" in a row is read as the next occupied seat in that direction, skipping vacant seats -- a standard convention in linear-seating puzzles with vacancies.
Step-by-step application:
Classify all twelve names by first letter. Vowel-starting -> Class A: Allen, Alpha, Emma, Ivory, Olive, Unique (6 people) -- note Ivory starts with the vowel “I”, which is easy to miss. Consonant-starting -> Class B: Coco, Den, Fame, Jack, London, Nick (6 people). This 6-and-6 split is what makes every “opposite” seat at the circular tables well-defined.
Seat Class A (dictionary order) and then Class B (reverse-alphabetical order) into the alternate seats -- seat 2, seat 4, seat 6, seat 8 -- of Row 1, then Row 2, then Row 3, in that sequence. The resulting row seating is shown below.
Row seating (only the occupied alternate seats are shown; seats 1, 3, 5, 7 are vacant in every row):
Row | Seat 2 | Seat 4 | Seat 6 | Seat 8 |
|---|---|---|---|---|
Row 1 | Allen | Alpha | Emma | Ivory |
Row 2 | Olive | Unique | Nick | London |
Row 3 | Jack | Fame | Den | Coco |
Table 1 (Class A, 6 people, facing the centre): Allen sits opposite the person second from the left in Row 2 (Olive) -> Allen opposite Olive. The next occupied seat to the right of Olive in Row 2 (Unique) sits second to the right of Allen. Alpha sits opposite Emma and is not adjacent to Olive -- this fixes every seat.
Table 2 (Class B, 6 people, facing the centre): the next occupied seat adjacent to Unique in Row 2 (Nick) is the anchor -- London sits second to the right of Nick. Jack sits opposite Den and is not adjacent to Nick. For the remaining condition, the occupied extreme seat of Row 2 itself is London -- using that as its own anchor would force London to sit opposite London, which is impossible -- so the extreme-seat condition must anchor on the other row's occupied end, Row 3's seat 8, Coco. Coco therefore sits diametrically opposite London (three seats away in a six-person circle is the same as directly opposite).
Table 1 seating (clockwise):
Position | Occupant |
|---|---|
1 | Allen |
2 | Alpha |
3 | Unique |
4 | Olive |
5 | Emma |
6 | Ivory |
Table 2 seating (clockwise):
Position | Occupant |
|---|---|
1 | Nick |
2 | Den |
3 | London |
4 | Fame |
5 | Jack |
6 | Coco |
Cross-check every Table 2 condition against this arrangement:
Nick's two neighbours are Den and Coco, not Jack -- satisfies “Jack does not sit adjacent to Nick.”
Jack sits diametrically opposite Den -- satisfies “Jack sits opposite Den.”
London sits exactly two seats to the right of Nick -- satisfies the second-to-the-right condition.
Coco sits diametrically opposite London, consistent with the extreme-seat condition once it is anchored on Row 3 rather than the self-referential Row 2 reading.
Result: the seat diametrically opposite Coco at Table 2 is occupied by London, and London is exactly the occupant of the (only occupied) extreme seat of Row 2 -- so the correct description is “the one who sits at extreme end in row 2.”
