There are four questions based on the same puzzle. Answer the questions based on the given information
A, S, O, D, F, T are members of a family consisting of 3 men and 3 women among whom there are two married couples. We also known that:
I. O is the son of S
II. T is the daughter of D
III. F is the grandson of A
IV. D is the mother of a girl and a boy
V. S is not the father of O
VI. All the relationship mentioned above are between these six persons only.
D's husband is?
- A.
O
- B.
F
- C.
A
- D.
None of these
Show answer & explanation
Correct answer: A
Concept: In a family-tree puzzle, first fix the gender of each ambiguous name using any father/mother clue, then place every person into a generation and pair up spouses so that each stated parent-child link is satisfied — the given totals (3 men, 3 women, exactly 2 married couples) act as a check on the tree built.
Clue I says O is a child of S; clue V says S is not the father of O, so S is female — S is O's mother.
With exactly two married couples in the family and O being S's child, S's husband is the remaining older-generation person, A; so A and S form the first couple, and O is their son.
Clue III says F is the grandson of A. Since O is the only child of A and S, F must be O's child (A's grandson through O).
Clue IV says D is the mother of a girl and a boy, and clue II says T (a girl) is D's daughter; the boy from clue IV must therefore be F (established in the previous step) — so D is the mother of F and T.
Since F and T are the children of both O (step 3) and D (step 4), O and D form the second married couple in the family.
Cross-check: the men are A, O and F, and the women are S, D and T — three of each — with exactly two married couples, (A, S) and (O, D), matching every clue, including that all relations hold only among these six people.
So D's husband is O.
