P and Q are brothers, R and S are sisters. P's son is S's brother. How is Q related to R?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Uncle
The statements are read one link at a time, starting from the one that ties the two families together:
“P’s son is S’s brother”: S has the same father, so S is P’s daughter (S is a sister, so female).
R and S are sisters, so R is also P’s daughter.
P and Q are brothers, so Q is the brother of R’s father, that is, R’s uncle.
