Directions : Study the following information carefully to answer the given questions:
Ten family members are sitting in two parallel rows containing five people each, in such a way that there is an equal distance between adjacent persons. In row–1 A, B, C, D and E are seated and all of them are facing north. In row-2 P, Q, R, S and T are seated and all of them are facing south. Therefore, in the given seating arrangement each member seated in a row faces another member of the other row.
P faces the one who sits 2nd to the left of his nephew. One person sits between P’s nephew and P’s mother. A is the sister-in-law of D who is not married. S is the granddaughter of B who sits left of P’s mother but not just left. R is the only brother of D who is the only immediate neighbour of B’s wife. Q is the husband of S and sits 2nd to the right of R’s father. A is the daughter of E and faces to the one who sits 2nd to the right of Q’s wife. P is the brother-in-law of R who is the father of C. T’s son sits just right of C’s brother-in-law. A’s father-in-law sits at one of the extreme ends. Both D and A are of same gender but opposite to C’s gender. B is not father 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.
P
- B.
S
- C.
R
- D.
B
- E.
T
Show answer & explanation
Correct answer: B
Concept
In a "four are alike, one is not" question, the four that form a group all share one single hidden attribute, and the odd one is the member that lacks it. For a family-arrangement puzzle the usual shared attribute is gender: you fix each named person's sex from the kinship clues, then the group of one gender is the set, and the lone member of the other gender is the answer. So the task is not really about seats — it is to read off each person's gender from how they are related to others.
Fixing each person's gender from the clues
Take only the five names in the options and ask what the kinship clues force about each one's sex:
R is the father of C and the only brother of D — being a father and a brother, R is male.
T is the father of R (and D): R’s father must be one of the men, but it cannot be E (E’s child A is R’s wife, so A cannot also be R’s sister) and it is not B (B is stated not to be R’s father), which leaves T — so T is male.
B has a wife (“B’s wife”) and is the grandfather of S — being a husband and grandfather, B is male.
P is the brother-in-law of R; “brother-in-law” is itself a male relationship, so P is male.
S is the granddaughter of B and the wife of Q (“Q is the husband of S”) — being a granddaughter and a wife, S is female.
Applying the grouping
Lining the five up by the gender just derived: R, T, B and P are each male, while S is female. Four of the five share the single attribute "male", which is the group. The one member who does not share it is the female, S — so S is the person who does not belong to the group.
Cross-check
Confirm the split is clean and unique: there is exactly one female among the five (S) and exactly four males (R, T, B, P), so the odd-one-out by gender is unambiguous. A tempting alternative basis is "row" — four of the five sit in the south-facing row while B sits in the north-facing row — but in these arrangement puzzles the seating row is the given structure, not a shared characteristic of the persons; the single attribute the kinship clues are written to reveal is gender, which is the intended basis, and on gender the answer is S.
