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.

Four of the following five are alike in a certain way and thus form a group. Who among the following does not belong to the group?

The correct answer is Nick.

Step-by-Step Explanation:

Step 1: Divide the students into Class A and Class B

According to the given information, students whose names start with a vowel belong to Class A, and the rest belong to Class B.

There are 12 students in total: Allen, Fame, Emma, Alpha, Coco, Nick, Ivory, London, Olive, Unique, Jack, and Den.

• Class A (Names starting with vowels): Allen, Alpha, Emma, Ivory, Olive, Unique (Total 6 students)

• Class B (Names starting with consonants): Coco, Den, Fame, Jack, London, Nick (Total 6 students)

Step 2: Determine seating in the parallel rows

1. The students are arranged across three rows (Row 1, Row 2, Row 3). Each row has 8 seats, and all seats are facing north.

2. Students sit in alternative seats starting from the second seat from the left end of Row 1.

• Seats in each row are numbered 1 to 8 from left to right.

• Alternative seats starting from 2nd seat means students sit in seats 2, 4, 6, and 8 of each row. Thus, there are 4 students per row (3 rows × 4 seats = 12 students).

3. Seating Order Rule:

• Class A students are seated first in alphabetical order.

• Followed by Class B students in reverse alphabetical order.

• Filling order: Row 1, then Row 2, then Row 3.

Alphabetical order of Class A students:

1. Allen

2. Alpha

3. Emma

4. Ivory

5. Olive

6. Unique

Reverse alphabetical order of Class B students:

1. Nick

2. London

3. Jack

4. Fame

5. Den

6. Coco

Placing all 12 students sequentially into the alternative seats (2, 4, 6, 8):

• 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

Step 3: Analyze the group formation

Let's check the given options: Allen, Alpha, Ivory, Emma, Nick.

• Allen, Alpha, Emma, Ivory belong to Class A (and sit at Table 1).

• Nick belongs to Class B (and sits at Table 2).

Thus, Nick does not belong to the group formed by the other four options.
