AMCAT Logical Ability: Blood Relations 2

Question 1

Pointing to a woman, Ramesh said, 'She is the daughter of the only child of my grandmother.' How is the woman related to Ramesh?

Accepted Answer

Sister

Answer

Ramesh's grandmother's only child is Ramesh's parent. The woman is that parent's daughter, so she is Ramesh's sister.

Question 2

A is the father of B. C is the daughter of A. D is the brother of E. E is the daughter of B. Who is the grandmother of D?

Accepted Answer

Cannot be determined

Answer

D's parent is B (since D is brother of E, and E is B's daughter). B's mother is never mentioned, so D's grandmother cannot be determined.

Question 3

If X is the brother of Y, Y is the sister of Z, and Z is the son of W, then how is X related to W?

Accepted Answer

Son

Answer

Z is son of W, so W is Z's parent. Y is sister of Z, so Y is W's child. X is brother of Y, so X is W's son (since X is male).

Father of her uncle = her grandfather. Daughter of grandfather = her mother. Son of her mother = her brother.
