If X is the brother of the son of Y's son, how is X related to Y?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Grandson
Read the relation from the end, one step at a time:
Y’s son is a son of Y
The son of Y’s son is Y’s grandson
X is the brother of that grandson, so X is male and is another son of Y’s son, that is, another grandson of Y
