Verbal Reasoning - Blood Relation Test - Discussion

Option D is right. Option c would be correct if O is female. Since the gender is not known correctly could not justify the answer. If O is a Male then M will be the paternal uncle to N. If O is a Female then M will be the maternal uncle to N.

Paternal uncle (one's father's brother).
Maternal uncle (one's mother's brother).

@Mr krishna according to option 3. O may be either mother or father to N so without knowing the gender how can we decide. If gender mentioned as O is mother then answer is correct for option 3.

If the gender O is male then only option can be C. But the gender of O is not given. So, it can be maternal Uncle/Paternal Uncle which does not specify any of the option given. So, option is D none of the above.

Any one explain the difference between maternal uncle and uncle?

Maternal uncle means mothers brother and then paternal uncle is fathers brother uncle means we call generally our relatives.

Maternal uncle means mothers brother. So option C is the correct as it shows that relation.

But they have specifically mentioned "maternal uncle" so 'O' has to be female which is not clear from the question.

Answer D.

@ALL.

m+o means m is the brother of o, means M(male) and o(male or female).

o%n means n is the daughter of o, means n(female) and o(male or female).

Maternal uncle means MAMA. And in this question "O" does not show male or female. The option C is correct when "O" is female.

Case 1: When o female.

Answer M+O = m(male) is brother of o(female), O%M = n(female) is daughter of o(female). Then M is sister daughter of N.

Case 2: When O male.

Answer- M+O = m(male) is brother of o(male), O%M = n(female) is daughter of o(male). Then M is brother daughter of N.

So I can say the 4 option is correct.

Answer C is not right because in answer C, M and O is brother and N is daughter of O this shows M is the uncle of N not maternal uncle.

Good question and answer. It's very useful to prepare the Aptitude problems.
