Verbal Reasoning - Blood Relation Test - Discussion

@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.

As option D is correct. Because any of the above does not give the answer.
But the explanation given is also wrong that the gender of O is not known it's clearly that AxB A is the son of B(i.e male A).

In 1st M+OxN OxN O is son of N(i.e is male O).
In 1st we do not get the gender of N and in 3rd option, we did'nt get the gender of O.

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).

The answer is D. But I want to say that the explanation is given is not true given okay. I can explain why, the reason is in each option O's gender is given as in 1st O was the son of N, 2nd option O was N's son again and the last 3rd in option O is the daughter of N. But in explanation, they said O gender not Mentioned.

The question is mentioned that material Uncle. Mother's Brother is material uncle. Father's brother is paternal uncle. According to the question, O is either Father or mother of N, the gender of O is not given. So Answer C is not satisfied. And the correct answer is D.

No answer is not c because maternal uncle is nothing but mama in hindi & answer C implies chacha in hindi hence it is not correct but solution proposed that D is also not right because no condition is satisfying the given condition hence D is correct.

C is the right answer as question demand for the relation between M and N so the gender of the O does not really matter In both odds (If O is mother or father) M will remain the maternal uncle of N.

So, (C) is the right answer.

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.

Option C is right because there is no relation of O and we can not take O as a mother maybe it is a father so we can not call M is maternal uncle because there are possibilities of paternal uncle also.

How can we say that sex of O is not known?

It is clearly mentioned in statement that A x B means A is the son of B. So in option [A] O x N mean O is son of B. It means O must be a Male person.
