Question 1

Introducing a man, a woman says: 'His mother is the only daughter of my father.' How is the woman related to the man?

Accepted Answer

Mother

Answer

The only daughter of the woman's father is the woman herself — so the man's mother is the woman herself, making her his mother.

Question 2

A is B's father's father. C is A's daughter-in-law. B is C's son. How is B related to A?

Accepted Answer

Grandson

Answer

A is B's father's father — that means A is B's paternal grandfather, so B is A's grandson.

Question 3

A woman walks 4 km south, turns east and walks 3 km. What is the straight-line distance from her starting point?

Accepted Answer

5 km

Answer

Using the Pythagorean theorem: √(4² + 3²) = √(16 + 9) = √25 = 5 km.

Question 4

X is Y's brother. Y is Z's father. Z is W's son. How is X related to W?

Accepted Answer

Uncle

Answer

Z is W's son, and Y is Z's father — so Y is W's grandfather (Z's father is W's parent's sibling... wait: Z is W's son means W is Z's parent; Y is Z's father means Y = W. Rechecking: Z is W's son → W is Z's parent; Y is Z's father → Y is Z's father = W (if W is male). Then X is Y's brother = W's brother = W's sibling. X is W's uncle if generation differs, but X is Y's brother and Y=W, so X is W's brother.
