Correct Answer: b) Father

Explanation:
1. "Mother's daughter" → Could be Shalini herself or her sister
2. "Husband of mother's daughter" → If daughter is Shalini: her father
Alternative: If Shalini has sisters, it could also be brother-in-law

Correct Answer: a) Daughter-in-law

Explanation:
1. "Only son of my father" → Rohan himself (if he has no brothers)
2. "Wife of the only son" → Rohan's wife
3. But "daughter-in-law" suggests this is from parent's perspective
Alternative Interpretation: If Rohan is female, "only son" would be her brother
Most Likely: Speaker is parent referring to son's wife

Correct Answer: b) Daughter-in-law

Explanation:
1. P and Q are siblings (P brother, Q sister)
2. Q is sister of R → R is sibling of P and Q
3. R is husband of S → S is R's wife

Therefore, S is daughter-in-law of T
Family Tree:
T
├── P
├── Q
└── R (married to S)

Correct Answer: a) Daughter

Explanation:
1. A is father of B → B is child of A

Key Point: The statement implies B is female
Short Trick: When "not son" is specified for a child, it means daughter

Correct Answer: d) Father

Explanation:
1. "Your mother's daughter-in-law" → B's mother's daughter-in-law
2. This person is A's mother → Therefore A's mother is married to B or B's sibling
3. Most direct relation: B is father of A (making A's mother B's wife)
Family Tree:
B (father)
└── A (child)
Where A's mother is B's wife

Correct Answer: a) Aunt

Explanation:
1. "Brother's wife" → Sister-in-law (from Ramesh's perspective)
2. "Mother of brother's wife" → Mother of sister-in-law
3. This would typically be Ramesh's aunt (father's or mother's sister)
Family Tree:
Ramesh's Parents

└── Brother (married to wife)
Wife's Mother → Ramesh's aunt

Correct Answer: c) Grandmother

Explanation:
1. Y is daughter of Z → Z is parent of Y
2. X is son of Y → X is grandchild of Z
3. Since Y is daughter (female), Z is most likely grandmother
Family Tree:
Z (grandmother)
└── Y (mother)
└── X (son)
Short Trick: When a parent-child chain involves a daughter, the grandparent is typically grandmother

Correct Answer: a) P is the father of R

3. Therefore: P is father of Q and R (since Q and R are siblings)
Family Tree:
P
├── Q (daughter)
└── R (child)
Short Trick: Solve code-based relations from left to right, building the family tree step by step

Note: E's gender isn't specified, but "mother of E" is correct regardless

Correct Answer: b) Brother

Explanation:
1. "Sister's husband" → Brother-in-law (from the man's perspective)
2. But the man is seeing his sister's husband → which means he is the brother of the sister whose husband he's seeing
3. Therefore, the man is the brother of the sister, making him the brother-in-law of the husband
Note: The direction information is irrelevant to the relationship

Correct Answer: c) Brother

Explanation:
1. "My grandfather's only son" → Could be Nita's father (if no uncles)
