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 fourth to the left of London in rows-based arrangement?
- A.
Olive
- B.
Unique
- C.
Allen
- D.
Fame
- E.
Coco
Show answer & explanation
Correct answer: B
Concept
In a rows-based arrangement where everyone faces north, a person's left hand points toward the smaller seat numbers (the west / left end) and the right hand toward the larger seat numbers. "Nth to the left" is counted by seat positions, including any vacant seats in between, not by skipping empty chairs. So fixing every student's seat first, then counting positions, is the whole method.
Building the seating
Split the 12 students by the vowel rule. Class A (names starting with a vowel): Allen, Alpha, Emma, Ivory, Olive, Unique in dictionary order. Class B (the rest): Nick, London, Jack, Fame, Den, Coco in reverse alphabetical order. They occupy only the alternative seats 2, 4, 6, 8 of each row, Class A first then Class B, filling Row 1, then Row 2, then Row 3.
Row 1 (seats 2,4,6,8): Allen, Alpha, Emma, Ivory.
Row 2 (seats 2,4,6,8): Olive, Unique, Nick, London.
Row 3 (seats 2,4,6,8): Jack, Fame, Den, Coco.
Applying it to London
London sits in Row 2 at seat 8, the right (east) end. Facing north, four positions to London's left means counting outward from seat 8 toward smaller seat numbers, one seat at a time, including vacant seats:
1st to the left = seat 7 (vacant).
2nd to the left = seat 6 (Nick).
3rd to the left = seat 5 (vacant).
4th to the left = seat 4 (Unique).
Cross-check
The circular-table conditions govern only the Table 1 / Table 2 question, not this one, so they are deliberately ignored here. Within Row 2 the only seat that is exactly four positions west of seat 8 is seat 4, and that seat holds Unique, so the answer is Unique.
