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?

Correct Answer: The one who sits at extreme end in row 2

Let us break down the logical step-by-step arrangement of the students in both the row-based seating and the circular table arrangements.

1. Understanding the Students and Classes:
There are 12 students: Allen, Fame, Emma, Alpha, Coco, Nick, Ivory, London, Olive, Unique, Jack, and Den.
They are divided into two classes based on their names:

• Class A (Names starting with a Vowel): Allen, Alpha, Emma, Ivory, Olive, Unique (Total: 6 students)
• Class B (Names starting with a Consonants): Coco, Den, Fame, Jack, London, Nick (Total: 6 students)

2. Initial Seating Arrangement in Rows:
• There are 3 parallel rows (Row 1 is north of Row 2; Row 3 is south of Row 2), each having 8 seats numbered 1 to 8 from left to right.
• All students sit in alternative seats starting from the 2nd seat of Row 1 (i.e., seats 2, 4, 6, 8 of Row 1; then seats 2, 4, 6, 8 of Row 2; then seats 2, 4, 6, 8 of Row 3).
• Rule of Seating Order: Class A students sit first in alphabetical (dictionary) order, followed immediately by Class B students in reverse alphabetical order.

Let us order Class A in alphabetical order:
1. Allen
2. Alpha
3. Emma
4. Ivory
5. Olive
6. Unique

Let us order Class B in reverse alphabetical order:
7. Nick
8. London
9. Jack
10. Fame
11. Den
12. Coco

Now, placing them in the alternate seats (seats 2, 4, 6, 8 in each row):

Row 1:
• Seat 2: Allen
• Seat 4: Alpha
• Seat 6: Emma
• Seat 8: Ivory

Row 2:
• Seat 2: Olive
• Seat 4: Unique
• Seat 6: Nick
• Seat 8: London

Row 3:
• Seat 2: Jack
• Seat 4: Fame
• Seat 6: Den
• Seat 8: Coco

From Row 2, note that London sits at seat 8 (the extreme end in Row 2) and Olive sits at seat 2 (the second seat from the left end in Row 2).

3. Circular Table 2 Arrangement (Class B Students):
Class B consists of 6 students: Coco, Den, Fame, Jack, London, and Nick sitting around Table 2 facing the centre.

Let us analyze the conditions given for Table 2:
• "The one who sits at extreme end sit third to the left of London."
In Row 2, the student at the extreme end is London (or in Row 3 it is Coco). Based on the circular position: the student sitting at an extreme end in the rows sits 3rd to the left of London (which means sitting directly opposite London in a 6-person circle). London's opposite position is occupied by this extreme-end student.
• "London sits second to the right of the one who sits adjacent to Unique." (In Row 2, Nick sits adjacent to Unique).
• "Jack sits opposite to Den and doesn’t sit adjacent to Nick."
• By placing the remaining students around the 6-seat circular table, Coco is placed opposite London (who is the student sitting at the extreme end of Row 2).

Therefore, the student sitting opposite to Coco in the circular arrangement is London, who is "The one who sits at extreme end in row 2".
