Vedclass · Answer

(A) To determine if $Q$ is the maternal uncle of $P$,we need to analyze the relationships:$1$. $A + B$ means $A$ is the son of $B$.$2$. $A - B$ means $A$ is the husband of $B$.$3$. $A 	imes B$ means $A$ is the sister of $B$.For $Q$ to be the maternal uncle of $P$,$Q$ must be the brother of $P$'s mother.Let's analyze option $B$: $P - B + R 	imes Q$.- $P - B$ means $P$ is the husband of $B$.- $B + R$ means $B$ is the son of $R$.- $R 	imes Q$ means $R$ is the sister of $Q$.This implies $R$ is the mother of $B$,and $Q$ is the brother of $R$. Since $B$ is the son of $R$ and $Q$ is the brother of $R$,$Q$ is the maternal uncle of $B$. This does not make $Q$ the maternal uncle of $P$.Let's re-evaluate the requirement: $Q$ is the maternal uncle of $P$. This means $P$ is the child of $Q$'s sister.Looking at $P + B - R 	imes Q$:- $P + B$ means $P$ is the son of $B$.- $B - R$ means $B$ is the husband of $R$.- $R 	imes Q$ means $R$ is the sister of $Q$.Since $B$ is the husband of $R$ and $R$ is the sister of $Q$,$B$ is the brother-in-law of $Q$. Since $P$ is the son of $B$ and $R$,$Q$ is the maternal uncle of $P$. Thus,the correct option is $A$.

If $A + B$ means $A$ is the son of $B$,$A - B$ means $A$ is the husband of $B$,and $A \times B$ means $A$ is the sister of $B$,then which of the following shows the relation $Q$ is the maternal uncle of $P$?
