Question

A family has seven members, A, B, C, D, E, F and G. Among them there are three married couples. B, an engineer, is the father of E, who is a student. F, a contractor, is the grandfather of E. C is the daughter-in-law of D, who is a professor. G, a doctor, is the uncle of the student E. Among the seven members there is one journalist, one housewife and one student. C is the sister-in-law of B. The student, E, is single.

Who is E's aunt?

• A. D
• B. A
• C. G
• D. C

Hint:

An aunt can be the wife of your father's brother; since G is B's brother, G's wife C is E's aunt.

Answer 1

The Correct Option is D

Step 1: Go option by option using generation and gender.
An aunt must be female and must belong to the parents' generation, not the grandparents' generation and not E's own generation.

Step 2: Eliminate on generation.
D sits in the grandparents' generation alongside F, since C is described as D's daughter-in-law, meaning D is a generation above C and B. That rules out D as an aunt.

Step 3: Eliminate on role.
A, taken as B's wife, would be E's own mother. A parent is not an aunt, so A is ruled out. G is male, and the family already needs a female for "aunt," so G, described as uncle, is also ruled out on gender alone.

Step 4: Confirm the remaining name.
That leaves C, who sits in the same generation as B (she is D's daughter-in-law, same level as B) and is female. Since C is married to G, B's brother, she becomes E's aunt through marriage, fitting every requirement, right generation and right gender, that the others failed.

Final Answer:
E's aunt is C. \[ \boxed{\text{C}} \]
