Types of Blood Relations Topic:


Relations:

It is necessary to have knowledge about the relations to solving the questions related to the relation.

1. Mother’s (or) Father’s sister – Aunt

2. Mother’s (or) Father’s father – Grand father

3. Mother’s (or) Father’s mother – Grand mother

4. Son’s wife – Daughter in law

5. Daughter’s husband – Son in law

6. Husband’s (or) Wife’s father – Father in law

7. Husband’s (or) Wife’s mother – Mother in law

8. Husband’s (or) Wife’s brother – Brother in law

9. Husband’s (or) Wife’s sister – Sister in law

10. Sister’s husband – Brother in law

11. Brother’s (or) Sister’s son – Nephew

12. Brother’s (or) Sister’s daughter – Niece

13. Mother’s (or) father’s son – Brother

14. Mother’s (or) Father’s Daughter – Sister

15. Mother’s brother – Maternal Uncle

16. Father’s Brother – Paternal uncle

Remark: - A relation on the mother’s side is called ‘maternal’ while that on the father’s side is called ‘paternal’. Thus, mother’s brother is ‘maternal uncle’ while father’s brother is ‘paternal uncle’.

Type 1 : Deciphering Jumbled up Descriptions

In this type of questions, a roundabout description is given in the form of certain small relationships and you are required to analyse the whole chain of relations and decipher the direct relationship between the persons concerned.

Ex.1. Ponting towards a person, a man said to a woman, “His mother is the only daughter of you father.” How is the woman related to that person?

(A) Daughter 

(B) Sister 

(C) Mother 

(D) Wife

Solution:

The only daughter of woman’s father is she herself. So, the person is woman’s son, i.e. the woman is the person’s mother. Hence, the answer is (C)

Ex.2. Pointing to a lady in the photograph, Shaloo said, “Her son’s father is the son-in-law of my mother.” How is Shaloo related to the lady ?

(A) Aunt

(B) Sister 

(C) Mother 

(D) Cousin

(E) None of these

Solution:

Lady’s son’s father is lady’s husband. So, the lady’s husband is the son-in-law of Shaloo’s mother, i.e. the lady is the daughter of Shaloo’s mother. Thus, Shaloo is the lady’s sister. Hence, the answer is (b).

Type 2 : Puzzle Relation 

In this type questions, mutual blood relations of more than two persons are mentioned the candidate is required to analyse the given information, work out a family chart and then answer the given question.

Ex.1. A family has man, his wife, their four sons and their wives. The family of every son also ahs 3 sons and one daughter. Find out the total number of male members in the whole family.

(A) 4

(B) 8

(C) 12

(D) 17

Solution:

The male members in the family are :

(i) The man himself:

(ii) His fours sons, and 

(iii) His (3×4) = 12 grandsons.

Hence, total number of male members = (1+4+12) = 17.

So, the answer is (d).

Ex.2. A and B are brothers. C and D are sister. A’s son is D’s brother. How is B related to C?

(A) Father 

(B) Brother 

(C) Grand father 

(D) Uncle 

(E) None of these 

Solution:

Clearly, B is the brother of A, A’s son is D’s brother. This means D is the daughter of A. Since C and D are sisters, C is also the daughter of A.

So, B is the uncle of C. Hence, the answer is (d).

Type 3 : Coded Relation 

In such questions, the relationships are represented by certain specific codes or symbols such as +,-,*,$,%,etc. The candidate is then required to analyse some given codes to determine the relationship between a set of person, or to express a given relationship in the coded form.

Ex.1. Read the following information carefully to answer to answer the questions given below : 

(i) ‘A×B’ means ‘A is the brother of B;

(ii) ‘A÷B’ means ‘B is the father of A;

(iii) ‘A+B’ means ‘A is the sister of B;

(iv) ‘A–B’   means ‘A is the mother of B;

Q.1. Which of the following means ‘Q is the paternal uncle of K’?

(A) K × P ÷ M × Q

(B) K × B ÷ N × Q × D

(C) Q × L ÷ R × K

(a) Only (A)

(b) Only (B) 

(c) Only (C)

(d) Both (A) and (B)

(E) None of these 

Solution:

‘K × B ÷ N × Q × D’ means ‘K is the brother of B, whose father is N, who is the brother of Q, who in turn is the brother of D’ Thus, N is the father of K, and Q is the brother of N.So, Q is the paternal uncle of K. 

Thus, Only (B) represents the correct relation. Hence, the answer is (b).

Ex.2. Which of the following statement is/are superfluous to answer the above question?

(A) (i) Only

(B) (ii) Only

(C) (iii) Only

(D) Only (iii) and (iv) 

(E) None of these.

Solution:

Clearly, we used only (i) and (ii) to answer the above question, while (iii) and (iv) are superfluous. Hence, the answer is (d).

Trick Example to Solve Blood Relation Question:


* If the question is "How is A related to B". Then you must know the gender of A to answer the question.

* Without knowing A's gender, you cannot determine the relation from A to B

* If a person is Uncle or Aunt to "A", A is that person's nephew (if A is Male) or niece (if A is female).

* Cousin is a common Gender (I mean, you can use this word for both Male and Female).

Example.1. A says to B, "you are the son of my grandfather’s only son".

(1) How is B related to A?

(2) How is A related to B?

Solution: 

B is Brother of A.

My grand father's only son = A's father (grand father's only son means only ONE son. No other son and no daughter also).

A is either brother or sister to B.

A and B are siblings. B is brother to A as we know the Gender of B. But we don’t know the Gender of A. So we can’t say whether A is Brother or Sister to B.
