Question

Read the following information carefully and answer the question given below:-

$A+B$ means $A$ is the daughter of $B$;
$A-B$ means $A$ is the husband of $B$;
$A\times B$ means $A$ is the brother of $B$.

If $P+Q-R$, which one of the following is true?

• A. $R$ is the mother of $P$
• B. $R$ is the sister in law of $P$
• C. $R$ is the aunt of $P$
• D. $R$ is the mother-in-law of $P$

Answer 1

The correct option is A $R$ is the mother of $P$

$P+Q\to P$ is the daughter of $Q$
$Q-R\to Q$ is the husband of $R$
$\therefore Q$ and $R$ are husband and wife and they have a daughter $\to P$
So $R$ is the mother of $P$
Hence, option 'A' is correct.
