Read the information carefully and answer the questions given below:
Fourteen persons are sitting in two parallel rows containing seven persons each. In row 1 - A, B, C, D, E, F and G are seated and all of them are facing north. While P, Q, R, S, T, U and V are sitting in row-2 and facing south direction but not necessarily in the same order. Persons of row 1 face the persons of row 2. Q sits two places away from the one who faces E. E is the only immediate neighbour of D. U faces the one who sits third to the right of C. The number of persons sit to the right of Q is same as the number of persons sit to the left of G. B sits second to the left of G. One person sits between R and V and both of them do not sit at the extreme ends. S sits right of T but not sit at the extreme ends. A faces the one who sits second to the right of R.
Four of the following five are alike in a certain way and hence form a group. Who among the following does not belong to that group?
- A.
T
- B.
F
- C.
S
- D.
U
- E.
G
Show answer & explanation
Correct answer: A
Concept
In an "odd-one-out" grouping question, four of the five named persons share one common positional property and the fifth is the exception. The method is fixed: first determine the complete seating from the constraints, then read off the property common to four of the listed persons and identify the one who fails it.
Building the arrangement
Two parallel rows of seven face each other. Row 1 (A, B, C, D, E, F, G) faces north; Row 2 (P, Q, R, S, T, U, V) faces south, and Row 1 position i faces Row 2 position i. Number the seats 1 to 7 from the observer's left. Apply the clues in order:
"E is the only immediate neighbour of D" forces D to an extreme end with E in the seat next to it.
"B sits second to the left of G" plus "persons to the right of Q equal persons to the left of G" place G at seat 4 of Row 1, with B at seat 2.
"U faces the one third to the right of C" places C at seat 3 (so the seat third to its right, seat 6, is the one U occupies in Row 2), and the remaining Row 1 letters A and F then sit at seats 1 and 5, giving Row 1 = A, B, C, G, F, E, D.
"A faces the one second to the right of R" fixes R at seat 3 of Row 2 (A is at seat 1, which it faces). "One person sits between R and V, neither at an end" puts V at seat 5. "Q is two seats from the person facing E": E sits at seat 6, so its facer is at seat 6, and Q lands at seat 4.
"S is right of T, neither at an end" with the remaining seats fills Row 2 = P, S, R, Q, V, U, T.
The unique seating that satisfies every clue (seats 1 to 7 left to right, facing pairs aligned vertically):
Seat (left to right) | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|
Row 1 (faces north) | A | B | C | G | F | E | D |
Row 2 (faces south) | P | S | R | Q | V | U | T |
So the face-to-face pairs are A-P, B-S, C-R, G-Q, F-V, E-U, and D-T.
Applying the group rule
For each listed person, look at the person they face and check whether that faced person has a seat-mate immediately to the right (in that person's own facing direction):
F faces V; V has a person seated to its right.
S faces B; B has a person seated to its right.
U faces E; E has a person seated to its right.
G faces Q; Q has a person seated to its right.
T faces D; D sits at the extreme end of its row and has no one to its right.
Cross-check
The same distinction appears directly in the seats: D is the only one of the five faced persons placed at an extreme end, and equivalently T is the only one of the five listed persons seated at an extreme end of its own row (seat 7). Both readings of the common rule isolate the same person, so the choice is unambiguous.
Result
T is the person who does not belong to the group.
