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.
Which among the following statement is true?
- A.
Fame doesn’t sit opposite to Nick.
- B.
Allen and Olive sit in the same row
- C.
Unique sits second to the right of Olive in row 2
- D.
Den sits in row 2
- E.
Coco doesn’t sit at the extreme end
Attempted by 1 students.
Show answer & explanation
Correct answer: C
Concept
In a linear-row seating puzzle with a fixed filling rule, you must first build the exact seat map before testing any statement. Two ideas govern this layout: (1) names are grouped and ordered by a stated rule (here, vowel-start names = Class A in dictionary order, consonant-start names = Class B in reverse-alphabetical order), and (2) seats are filled in a fixed pattern (alternate seats from the 2nd seat of each row, top row first, then downward). Once the map is fixed, a positional statement is judged purely by reading the map.
Application — build the seat map
Class A (vowel-start), dictionary order: Allen, Alpha, Emma, Ivory, Olive, Unique.
Class B (consonant-start), reverse-alphabetical order: Nick, London, Jack, Fame, Den, Coco.
Seats per row are filled at the 2nd, 4th, 6th and 8th positions only (alternate seats from the 2nd seat); the 1st, 3rd, 5th and 7th stay vacant. Each row therefore holds 4 students.
Place Class A first, continuing into Class B, filling Row 1, then Row 2, then Row 3 in that order.
This yields the following map (only occupied seats shown; all face north, so each student's right hand points toward the higher seat numbers):
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 |
Reading the statement under test
Olive occupies Seat 2 of Row 2. Counting seats toward her right (higher seat numbers), the seat two places to her right is Seat 4, which is Unique. The puzzle itself counts row positions this way: its own clue "the one who sits second from the left end in row 2" lands on Seat 2 (Olive), confirming that row positions are counted by seat. Hence "Unique sits second to the right of Olive in row 2" reads true off the map.
Cross-check — the other statements
"Allen and Olive sit in the same row": Allen is in Row 1 and Olive is in Row 2 — different rows, so this is false.
"Den sits in row 2": Den is placed in Row 3 (Seat 6), not Row 2 — false.
"Coco doesn't sit at the extreme end": Coco occupies Seat 8 of Row 3, the east-most occupied seat, i.e. an extreme end — so this statement is false.
"Fame doesn't sit opposite to Nick": this depends on the Table-2 circular arrangement, whose stated conditions are internally inconsistent (they refer to Unique, who is at Table 1, and to an "extreme end", which is a row idea), so it cannot be established as true.
Therefore the statement "Unique sits second to the right of Olive in row 2" is the one that is true.
