Directions: Read the given information carefully and answer the questions based on it:
A certain number of persons sit in a row facing north. The known persons like different colors. On counting from left, the persons at even positions are managers and the persons at odd positions are associates.
Four persons are in between A and the one who likes red. G sits third to the left of A. The one who likes blue sits exactly between G and the one who likes red. Four persons are in between C and the one who likes blue. The one who likes pink sits immediate right of C. D sits three persons sit to the right of the one who likes pink. The number of persons sit to the right of D is equal to the square root of the number of persons sit between D and the one who likes red. T sits sixth to the left of H who sits adjacent to C. H likes pink and sits immediate right of the one who likes yellow. No one sits to the left of B who sits adjacent to T. The one who likes black sits fourth from right end. The one who likes grey sits second to the right of B and third to the left of the one who likes white.
Choose the incorrect combination.
- A.
G – grey - associate
- B.
D – black - associate
- C.
A – white - manager
- D.
T – blue - manager
- E.
B – yellow - associate
Show answer & explanation
Correct answer: E
Concept
In a linear-arrangement puzzle you fix the total length and every person's seat by chaining the positional clues, then read off each attribute. Two anchoring rules drive this set: (i) counting from the left, even seats are managers and odd seats are associates; and (ii) "X persons sit between" means the two seats are X+1 apart, while "Nth to the left/right" means exactly N seats away. A square-root clue only resolves to a whole row length when the gap it points to is a perfect square.
Application — building the row
No one sits left of B, so B is at the extreme left (seat 1); T is adjacent to B, so T is at seat 2.
T is sixth to the left of H, so H is at seat 8; H likes pink and sits immediately right of C, so C is at seat 7, and the yellow-liker (immediately left of pink H) is C.
Grey-liker is second to the right of B (seat 3) and third to the left of the white-liker (seat 6).
G is third to the left of A, |A − red| = 5, and blue sits midway between G and red. Solving these with C at 7 forces A at seat 6 (white), G at seat 3 (grey), red at seat 1 (B) and blue at seat 2 (T).
D is three seats right of pink (seat 8), so D is at seat 11. Black is fourth from the right end, which (for the length below) is seat 11 — so D likes black.
The seats to the right of D equal the square root of the seats between D and red. With D at 11 and red at 1 there are 9 seats between them; √9 = 3, so exactly 3 seats lie to D's right, giving a total of 14 seats — a consistent, whole-number fit.
Resulting arrangement
Position | Person | Colour | Role |
|---|---|---|---|
1 | B | Red | Associate |
2 | T | Blue | Manager |
3 | G | Grey | Associate |
6 | A | White | Manager |
7 | C | Yellow | Associate |
8 | H | Pink | Manager |
11 | D | Black | Associate |
Cross-check — reading the options
Applying the even=manager / odd=associate rule to the table: B sits at seat 1 (odd → associate) and likes red. The question asks for the INCORRECT combination, so the answer is the pairing that does not match this grid.
G at seat 3 → grey, associate — matches the grid, so this is a correct combination.
D at seat 11 → black, associate — matches the grid, so this is a correct combination.
A at seat 6 → white, manager — matches the grid, so this is a correct combination.
T at seat 2 → blue, manager — matches the grid, so this is a correct combination.
B at seat 1 → red, associate; pairing B with yellow contradicts the grid, so this combination is the incorrect one.
