(a) ‘M $$\times$$ N’ means ‘N is brother of M’
(b) ‘M $$\div$$N’ means ‘M is father of N’.
(c) ‘M - N’ means ‘M is sister of N’
(d) ‘M + N’ means ‘M is mother of N’
Which of the following means J is nephew of R ?
Let us start with the first option.
Option A: J X T + R means that J is the brother of T who is the mother of R. The gender of R cannot be determined ( R can be nephew/niece).
Option B: K X R - J means that K is the brother of R who is the sister of J. All three of them are siblings.
Option C: J X T + R $$\div$$ K means that J is the brother of T. T is the mother of R. R is the father of K. Hence, J is the uncle of R. But the question asks whether J is the nephew of R.
Option D: J X T - R means that J is the brother of R. hence, the required relationship is not obtained.
Therefore, the correct answer is option E - none of the above.
