# Blood Relation

Logic Level 2

If $$P + Q$$ means $$P$$ is the brother of $$Q$$; $$P \times Q$$ means $$P$$ is the father of $$Q$$ and $$P - Q$$ means $$P$$ is the sister of $$Q$$, which of the following relation shows that $$I$$ is the niece of $$K$$?

Details

• The operations $$+,-,\times$$ are binary relations. I.e. $$P+Q\times R$$ means that $$P$$ is the brother of $$Q$$, and $$Q$$ is the father of $$R$$.
