Most of us are often confused when it comes to what to call which relative what. It is important to understand these thoroughly when tackling general blood relation problems in various banking exams like IBPS PO and others. We need to understand who is an uncle, aunt, cousin, grandmother, grandfather etc. We need to understand the difference between ‘maternal’ and ‘paternal’. Here is a short conversation among three children and their understanding about uncle, aunt and cousins relations.

Akshay – Hi Nikhil! Meet my cousin Bhavna.

Nikhil – Hey Bhavna!

Bhavna – Hello!

Nikhil – Cousin means who exactly?

Akshay – She is the daughter of my mother’s brother.

Nikhil – Oh! Your maternal cousin.

Akshay – Yes.

Bhavana – What does ‘maternal’ mean?

Akshay – ‘Maternal’ means relations from mother’s side. Relations from father’s side are called ‘paternal’ relations.

Bhanva – That means you are my paternal cousin.

Akshay – Exactly.

Bhavan – But why ‘cousin’? Why not ‘paternal brother’?

Nikhil – ‘Paternal brother’ is not used because we use the words ‘Brother’ & ‘Sister’ for those who share the same mother and father. On the other hand, the word ‘Cousin’ is one whose mother or father is the brother or sister of your mother or father. Got it?

Bhavan – Yeah! But what about male – female?

Akshay – For both pateranal or maternal brother and sister, we use the same word ‘cousin’.

Bhavana – Ok. Then what about aunty or uncle?

Akshay – It’s not aunty, dear. It’s aunt and uncle.

Bhavana – Ok, but are they maternal or paternal?

Nikhil – Both.

Bhavna – What do you mean?

Akshay – I’ll tell you. Aunt is your father’s sister or your father’s brother’s wife. This is from paternal side. The sister of your mother or your mother’s brother’s wife is your aunt from the maternal side.

Bhavana – Then uncle is your father’s brother or your father’s sister’s husband. This is from the paternal side. Your mother’s brother and your mother’s sister’s husband are both your maternal uncles. Right?

Nikhil – Correct!

Akshay – Same is for our grandfather and grandmother.

Bhavana – Yes, I got it, mother and father of our mother are maternal grandmother and grandfather whereas mother and father of our father are our paternal grandmother and grandfather.

Nikhil – And if we are using just grandmother or grandfather then they can be either paternal or maternal. Ok?

Bhavana – Yes. Got it!

Type Of Problems

  1. Single Person Blood Relations
  1. Mixed Blood Relations
  1. Coded Blood Relations

1.Single Person Blood Relations


These are Relations between two people only.

1(a) DIRECT Single Person Blood Relations :

Break the given sentence at is/was/as and resolve it from last point to is/was/as to get easy solution for the problem.

Carefully observe the given examples:

Ex – 1 :

Pointing to a lady Ravi said,” She is the only daughter of the father of my sister’s brother”. How is she related to Ravi?

Solution :

Break the given sentence at is.

From the last, in the view of Ravi,

My sister’s brother – brother

Father of brother – father

Daughter of father – sister

So,that becomes “she is my sister”

So, answer is sister.

Ex-2 :

John introduces Mary as the daughter of the only son of my father’s wife. How is Mary related to john?

Solution :

Break the given sentence at as.

Resolving from the last, In the view of john,

My father’s wife – mother

Only son of mother – himself i.e. john

Daughter of john– daughter.

So, answer is daughter.

NOTE : Sometimes they might ask like how is john related to Mary. In that case, answer is a father. So, don’t make answers without clear understanding in this type of problems.

1(b) INDIRECT Single Person Blood Relations :

Break the given sentence at is/was/as.

Resolve the sentence from last upto is/was/as.

And also resolve the sentence from the first upto is /was/as.

Then you will get the easy solution. Observe the below examples.

Ex-3 :

Pointing to a man in the photograph, a Woman says,” His mother’s only daughter is my mother”. How is man related to a woman?

Solution :

Break the sentence at is.

From the last, up to is : my mother – Woman’s mother

From the first, up to is : his mother’s only daughter – his sister

His sister = woman’s mother.

So, the answer is Mother’s brother i.e. Uncle.

If the question asks like how is woman related to that man? Then answer is sister’s daughter i.e. niece.

Ex-4 :

Introducing Suresh, Kalpana said,” His brother’s father is the only son of my grandfather”. How is Kalpana related to Suresh?

Solution :

Break the sentence at is.

From the last up to is: The only son of my grandfather – father

From the first up to is : his brother’s father – father

Suresh’s father = Kalpana’s father

So, they are brother & a sister.

Answer is sister.

NOTE : Like in the above type of problems From either ends if it is like

Father = Father Uncle= Uncle

Mother = Mother Aunt = Aunt

Then they both may be brothers/sisters / bother & sister depending upon their sex.

2. Mixed Blood Relations

In this, mutual blood relations depending on more than two persons mentioned. These type of problems can be solved with the help of diagrams. Follow these symbols in the diagram to avoid confusion.

+ Male candidate

– Female candidate

<=> Couple

——- Same generation i.e.brother –brother (or) sister-sister (or) sister to brother

_______ Different generations i.e. father-son (or) mother-son (or) father – daughter (or) Mother – daughter

The following list of generation might be helpful to you.

First generation : Grand father, Grand mother

Second generation : Father, Mother, Uncle, Aunt.

Third generation : Self, Sister, Brother, Sister in law, Brother in law

Fourth generation : Son, Daughter, Nephew, Niece.

Better to use the same generation in one horizontal row in the diagrams.

EX – 5 :

A and B are brothers and C and D are sisters. A’s son is D’s brother. How is B related to C?

Solution:

By using above notations we can draw the below diagram. A, B are taken ‘+’ and C, D

are taken as ‘-’. It seems that A, B belongs to one generation and C, D belongs to another generation.

So, A, B are taken in one horizontal row and C, D are taken in another horizontal line.

It says that A is C’s father. Father’s brother is an uncle. So, answer is uncle.

Sometimes they might ask paragraph questions in blood relations type problems.

EX – 6 :

Read the information carefully and answer the question given below it.

A family consists of 6 members P, Q, R, X, Y, Z.
Q is the son of R but R is not the mother of Q.
P and R are a married couples.
Y is the brother of R, X is the daughter of P.
Z is the brother of P.

Questions :

  • Who is the brother in law of R?
  • How many female members are there in the family?
  • How is Q related to X?
  • How is Y related to P?

Solution:

Draw the diagram with given instructions below.

  • Q is son of R. draw this one with thick line in different horizontal rows. Both are male so take as’+’.
  • Use <=> between P and R in same row, because they are couple.
  • Add Y to R with dotted line in same row.
  • Add X to P with thick line downwards to different row. Here, X is ‘–‘.
  • Add Z to P and take Z as ‘+’.
  • So, Q and X are brother & sister.

Answers :

  • Brother in law means wife’s brother i.e. Z
  • Two female members are there with ‘-‘ symbols i.e. P and X.
  • Q is brother of X.
  • Y is husband’s brother to P. i.e. brother in law.

3. Coded Blood Relations

In this type, relationships represented by codes and symbols like + , – , / , *. You have to analyze the required relation based on the given code. In this also you may need diagrammatic representation of problem to solve it. Use the same representation used in mixed blood relations. In the coding equation better to solve the code from the last letter.

Ex -7 :

If P+Q means P is the husband of Q, P/Q means P is the sister of Q, P*Q means P is the son of Q. how is D related to An in D*B+C/A?

Solution :

C/A – C is a sister of Q.

B+C/A – B is brother in law of A (sister’s husband – brother in law.

D*B+C/A – D is the nephew of A (sister’s husband’s son means sister’s son i.e. nephew).

So, answer is Nephew.

Understanding Complex Blood Relations

The easiest way to remember complex blood relations is to visualize them. Here are a few family trees to help you remember complex blood relations.

Family tree showing blood relations: Niece and Nephew

Note 1: For both male and female siblings, children of siblings are nieces and nephews where girl child is niece and boy child is nephew.

Note 2: The siblings become uncles and aunts to the children. A female sibling of your parent is an aunt. A male sibling of your parent is an uncle. This is true for both your father’s and your mother’s siblings.

Complex Blood Relations: Nephew & Niece - 1
Complex Blood Relations: Nephew & Niece – 1

 

 

Complex Blood Relations: Nephew & Niece - 2
Complex Blood Relations: Nephew & Niece – 2

Family tree showing blood relations: Father-in-law and Mother-in-law

Note 3: The word in-law is used to express relations which you get only after marriage or when a sibling gets married. But in the case of father-in-law and mother-in-law, you must be the one to marry.

Note 4: If you are a woman, the mother and father of your husband are your mother-in-law and father-in-law respectively. Similarly, if you are a man, the mother and father of your wife are your mother-in-law and father-in-law respectively

Note 5: For your father-in-law and mother-in-law, you are their daughter-in-law (if you are a woman) or their son-in-law (if you are a man).

Complex Blood Relations: Mother-in-law & Father-in-law - 1
Complex Blood Relations: Mother-in-law & Father-in-law – 1

 

 

Complex Blood Relations: Mother-in-law & Father-in-law - 2
Complex Blood Relations: Mother-in-law & Father-in-law – 2

Family tree showing blood relations: Brother-in-law and Sister-in-law

Note 6: If you are a man, then your wife’s brothers and sisters are your brothers-in-law and sisters-in-law. You also become a brother-in-law to your wife’s brothers and sisters. Similarly, if you are a woman, then your husband’s brothers and sisters are your brothers-in-law and sisters-in-law. You also become a sister-in-law to your husband’s brothers and sisters.

Note 7: When you have more than one brother-in-law and sister-in-law, they are called brothers-in-law and sisters-in-law. It would be wrong to call them brother-in-laws and sister-in-laws. But the group as a whole are called in-laws.

let us discuss some basic symbols to represent various relations in blood relation questions.

We always use + sign for male.

We always use – sign for female.

  • UntitledTo show the relation from one generation to another (Mother/Father to Son/Daughter), we use single arrow head.
  • To show the relation within the same generation (siblings/cousins), we use single arrow head.
  • To show the relation between husband & wife, we use double arrow head.

Let us see symbolic representation of various blood relations:

1. A is the father of B: Here we know the gender of A only. B can either be son or daughter.

111

2. A is the mother of B: Here we know the gender of A only. B can either be son or daughter.

112

3. B is the son of A: Here we know the gender of B only. A can either be father or mother.

113

4. B is the daughter of A: Here we know the gender of B only. A can either be father or mother.

114

5. B is the wife of A: Here we know the gender of both A and B.

115

6. A is the husband of B: Here we know the gender of both A and B.

115

7. A is the uncle of C: Here we know the gender of A only. B & C can be either male or female.

117

8. A is the aunt of C: Here we know the gender of A only. B & C can be either male or female.

118

9. C is the nephew of A: Here we know the gender of C only. A & B can be either male or female.

119

10. C is the niece of A: Here we know the gender of C only. A & B can be either male or female.

120

11. A is the paternal grand-father of C: Here we know the gender of A and B both.

121

12. A is the paternal grandmother of C: Here we know the gender of A and B both.

122

13. A is the maternal grandfather of C: Here we know the gender of A and B both.

123

14. A is the maternal grandmother of C: Here we know the gender of A and B both.

124

Blood relation questions can be asked in two different ways.

Type I: In this case, the blood relation is not coded.

Direction: M is the mother of B. A is the husband of M. N is the only brother of B. C is married to N. Q is the only child of C. N does not have any sister. J is the father of A.

Solution:

M is the mother of B.

q1

A is the husband of M.

q2

N is the only brother of B.

q3

C is married to N.

q4

Q is the only child of C.

q5

N does not have any sister (Which means B is definitely his brother).

q6

J is the father of A.

q7

Q.1) If A doesn’t have any grandson, then how is Q related to B?

  1. Can’t be determined
  2. Sister-in-law
  3. Daughter-in-law
  4. Niece
  5. Nephew

Solution: We can see that Q is either the grandson or granddaughter of A. But as per the question, A doesn’t have any grandson which definitely assures that Q is A’s granddaughter. So Q is B’s niece.

Q.2) How is A related to C?

  1. Uncle
  2. Can’t be determined
  3. Father-in-law
  4. Nephew
  5. Brother-in-law

Solution: A is N’s father and C is N’s wife. So A is the father-in-law of C.

Q.3) How is B related to J?

  1. Father
  2. Nephew
  3. Brother-in-law
  4. Brother
  5. Grandson

Solution: B is the son of J’s son. So B is the grandson of J.

Type II: In this case, the blood relation is coded.

Directions: Read the following information carefully and answer the question which follows:

‘A*B’ means A is the son of B.

‘A+B’ means A is the father of B.

‘A>B’ means A is the daughter of B.

‘A<B’ means A is the wife of B.

Q.4) What will come in place of the question mark (?), if it is provided that M is the grandmother of F in the expression ‘F*R<S?M’?

  1. >
  2. <
  3. +
  4. *
  5. Can’t be determined

Solution: F*R means F is the son of R.

q8

R<S means R is the wife of S.

q9

M is the grandmother of F (given already) which means M is either mother of S or R. So we can’t determine the answer for this questions using given options. So the answer is 5.

So we have seen two different ways in which blood relation questions can be asked. Sometimes blood relation concept is used in sitting arrangements as well to make those questions more tough. That application of blood relations will be discussed in basics of sitting arrangement.

Key points related to blood relations:

  • Never assume any person to be male or female if not specified in the question.
  • Step by step approach can always give the solution for blood relation questions, doesn’t matter the question is coded or simple one.

    Option D
    Explanation:
    B is brother of P. K is father of them. A is wife of P. N is daughter of P and A. N is son/daughter of P and A. T is married to N.
    Now:: C is mother of D. L is sister-in-law of D and M is daughter of L.
    Now there are two possibilities:
    First — D is sister of A and L is wife of D’s and A’s brother. But C has only 1 daughter so A and D cant be both daughters. So this cancels out.
    Second — D is sister of P. C is wife of K. Now L is sister-in-law of D and D is not married so L is daughter-in-law of C and K. Cannot be necessarily wife of B.
    C can have more children, thus L can be wife of  any other person too other than B.
