Verbal Reasoning - Blood Relation Test - Discussion

@All

Please read my explanation given below carefully.

[ Remember: Cousin = The child of one's aunt or uncle. ]

Case-1:
If {the Girl's uncle = Brother of Girl's Mother}
Then the answer will be 'Brother or Cousin'.

Case-2:
If {the Girls uncle = Brother of Girl's Father}
Then the answer will be 'Cousin'.

Among the given options, there is no option for 'Cousin'.
So, we have to choose 'Brother' as the correct answer.

Tips: Use elimination method, just ignore the options that are not suitable. Then the remaining one is 'Brother'.

Note: In what situation will the answer be Brother?

If {the Girl's uncle = Brother of Girl's Mother}
Then, the Father of Girl's Uncle = Girl's Grand_Father(G_F)

In case, G_F's daughter =(might-be)= Girl's mother.

In this situation only, the boy will be Brother to that Girl. Otherwise, the answer will be cousin.

Hope this will help you a bit. Have a nice day!

@All.

The answer is B according to the options given. Because my uncle can be both father's brother or mother's brother. If we take uncle as mother's brother then answer will be brother. Because daughter of father of her uncle is girls mother. Son of daughter is mother son. It means girl and boy are bother. But in case if we take uncle as father's brother than answer is cousin. But since cousin is not in options we can go for a brother.

@All.

Let's break down the statement to understand the relationships mentioned:

"He" - a boy
"The daughter of the father of my uncle" - a cousin of the girl's father (i.e., the girl's cousin).

"He is the son of the daughter of the father of my uncle" - the boy is the son of the girl's cousin.

Therefore, the boy is the cousin once removed of the girl. In other words, the boy is the girl's cousin's child.

@All.

Here, you can understand it properly.

In this type of question (son of the daughter of the father of my uncle) reverse the chain

i.e. solve it this way.

Father of uncle.
Daughter of the father of uncle.

Son of the daughter of the father of uncle.

So
1) Father of an uncle (dad)
2) Daughter of the father of uncle.
3) Son of the Mom.
(Son of the mummy is brother).

Hope you understand.

Girl said, "He is the son of the daughter of the father of my uncle". How is the boy related to the girl?

For this Kind of question solve from back to front we search keyword my in "" (quotations) , in the sentence my uncle means girl uncle, then father of girl uncle means her grandfather, the daughter of grandfather means either mother or aunt. Son of mother is brother. So answer is brother.

@Sundar. Good explanation. But there needs to be two corrections.

1. Your answer will be perfect when its given that "He is the son of the ""only"" daughter of the father of my uncle. ".

2. In Intro given by India bix, if its given simply as uncle, one has to take it as father's bro. One have to take it as mother's bro only when its given as maternal uncle. This is pointed by Sandeep.

Let's break down the statement:

"He is the son of the daughter of the father of my uncle."

"Father of my uncle" - This refers to the grandfather.
"Daughter of the father of my uncle" - This is the father's sister, which means the girl's father's sister.
"Son of the daughter of the father of my uncle" - This is the son of the girl's father's sister.

So, the boy is girl's cousin.

It is correct.

The logic is;

Father of girl's Uncle= Grandfather (May be from Mother side may be from Father sider)
1-IF grandfather from father side then answer will be "cousin".No option of cousin in answer so
2- Grandfather is from mother side now see girl's mother also grandfather's daughter not only her aunt that's why the answer is the brother.

The answer is either cousin or brother. Such dubiousness should be avoided while framing questions. Using the elimination process does not test any kind of logical reasoning skills in you, in fact it is an incorrect assumption on part of the content developer. Guys, since when have we started looking for the most logical answer amongst incorrect choices.

Through final conclusion, you will get to know that,

The son can be either cousin or brother of the girl, as a cousin is not in the given option it will be the brother of the girl.

Also, the relation between the girl and uncle, specifies that she is not the daughter of the uncle hence boy can't be a cousin of the girl.
