Reasoning “Grandson of my mother” can be Amit's son (the simplest and most common interpretation in such problems).The girl is the wife of that grandson ⇒ she is Amit's son's wife ⇒ Amit is her father-in-law. Note Other interpretations (e.g., nephew's wife) are possible in general, but standard test logic assumes the grandson is the speaker's son.

Accepted Answer

Decode each link A # B ⇒ A is mother of B. B $ C ⇒ B is brother of C (so B and C share parents). C * D ⇒ C is daughter of D (so D is a parent of C and hence of B). Reasoning Since A is the mother and D is the other parent of the same children (B and C), D must be the father.

Accepted Answer

Decode each segment N * P: N is the sister of P ⇒ N and P are siblings. P $ Q: Q is the mother of P. Q * M: Q is the sister of M ⇒ M is Q's brother (male). Link to N Since N and P are siblings and Q is P's mother, Q is also N's mother.M is Q's brother ⇒ M is the brother of N's mother ⇒ maternal uncle of N. Why others fail M = P + Q * N: Q becomes N's sister, not mother. N + P = Q * M: Implies Q is both father (via “=”) and sister (via “*”), a gender contradiction.

Data sufficiency (family roles): Who is A’s father?  Given: A and B are children of D. Which statements are necessary to identify A’s father? (1) C is the brother of A and the son of E. (2) F is the mother of B.  Choose the correct necessity conditi…

Accepted Answer

Analyze statements : C is A's brother and son of E ⇒ E is a parent of C (and likely A), but E's relation to D is unknown; cannot identify A's father. : F is mother of B. Since B is a child of D and already has mother F, D must be the father of B. Therefore D is male (father). A is also a child of D ⇒ A's father is D. Conclusion Statement (2) alone suffices; (1) alone does not.

Accepted Answer

Use (1) D's son is C's grandson ⇒ D is a child of C. Combine with (2) B is the sister of D, so B is also a child of C ⇒ B is C's daughter. Necessity (1) alone: identifies D as C's child, but B's gender is unknown ⇒ cannot say “daughter”. (2) alone: does not connect B/D to C at all. Conclusion Both (1) and (2) are required.
