(ii) ${}^{\prime }P-Q^{\prime }$ means 'P is the sister of Q'.
(iii) ${}^{\prime }P+Q^{\prime }$ means 'P is the father of Q'.

Which of the following represents 'M is the nephew of N'?

• A. $N-K+M$
• B. $N\times K÷M$
• C. $N÷K\times M$
• D. $N-K+M\times T$
• E. None of these

Answer 1

The correct option is D $N-K+M\times T$

From option (4) $N-K+M\times T$
N - K $\to$ N is the sister of K

K + M $\to$ K is the father of M.
M $\times$ T $\to$ M is the brother of T.
So, M is the nephew of N.
