Study the following information carefully and answer the questions given below.
(i) ${}^{\prime }P\times Q^{\prime }$ means 'P is the mother of Q'.
(ii) ${}^{\prime }P+Q^{\prime }$ means 'P is the sister of Q'.
(iii) ${}^{\prime }P÷Q^{\prime }$ means 'P is the father of Q'.
(iv) ${}^{\prime }P-Q^{\prime }$ means 'P is the brother of Q'.
Which of the following means 'M is the niece of R'?

• A. $M-T÷J-R$
• B. $R-T÷M-K$
• C. $R-T÷M+K$
  
  
• D. $R+T÷M+K$
  
• E. None of the above

Answer 1

The correct option is D $R+T÷M+K$


We can easily rule out the first three options as in all these options as M is male. M should be female for being the niece.
From option (d),

Here, R is the sister of T and T is the father of M.
So, M is the niece of R.
