Question

Study the following information and answer the questions given below.
(i) ${}^{\prime }P÷Q^{\prime }$ means 'Q is the father of P'.
(ii) ${}^{\prime }P\times Q^{\prime }$means 'P is the sister of Q'.
(iii) ${}^{\prime }P+Q^{\prime }$ means 'P is the brother of Q'.
(v) ${}^{\prime }P-Q^{\prime }$ means 'Q is the mother of P'.
Which of the following means R is the nephew of T?

• A. $R+N—Q\times T$
• B. $R–Q\times N\times T$
• C. $R-N\times T$
• D. $T+M÷R$
• E. $T–Q÷R$

Answer 1

The correct option is A $R+N—Q\times T$

If R is the nephew of T then the required equation must depict R as a male. Reject (b) and (c) because in these equations the symbol '—' denotes the sex of Q and N respectively. The sex of R remains unknown. Reject (d) and (e) because these equations depict R as older than T. Now, check (a).
Obviously, R is the nephew of T.
