Blood Relations is an important topic in the Analytical Ability and Logical Reasoning section of NIMCET. You may find these questions confusing when several family members, indirect relationships, different generations, or coded symbols are given together. A small mistake in identifying the gender, generation, or family connection can lead to the wrong answer.

NIMCET Blood Relations questions require you to understand how people in a family are connected and identify the relationship asked in the question. The PW NIMCET learning resources cover important reasoning concepts and question-solving approaches that can help you understand these relationships and solve different types of blood relation questions systematically. 

Basic Family Relationships in Blood Relations

Understanding common family terms makes it easier to interpret statements in reasoning questions.

Paternal Relations

Paternal relations are relationships on the father's side of the family.

  • Paternal grandfather: Father's father

  • Paternal grandmother: Father's mother

  • Paternal uncle: Father's brother

  • Paternal aunt: Father's sister

Maternal Relations

Maternal relations are relationships on the mother's side of the family.

  • Maternal grandfather: Mother's father

  • Maternal grandmother: Mother's mother

  • Maternal uncle: Mother's brother

  • Maternal aunt: Mother's sister

Other Common Relations

Some questions use basic family relationships without specifying the paternal or maternal side.

  • Sibling: Brother or sister

  • Cousin: Child of one's uncle or aunt

  • Nephew: Son of one's sibling

  • Niece: Daughter of one's sibling

  • Grandson: Son of one's son or daughter

  • Granddaughter: Daughter of one's son or daughter

  • Grandchild: Son or daughter of one's son or daughter

Knowing these terms helps you quickly understand direct and indirect family relationships and construct the correct family connection while solving NIMCET Blood Relations questions.

Symbols in NIMCET Blood Relation Coded Questions

Coded blood relation questions use symbols to represent different relationships. The meaning of a symbol is generally provided within the question, so candidates should not assume that a particular symbol always represents the same relationship.

For example, a question may define symbols in the following way:

Symbol

Possible Meaning

+

Brother or sister, depending on the question

Brother or husband, depending on the question

×

Mother or son, depending on the question

÷

Father or mother, depending on the question

The exact meaning of each symbol must always be taken from the question. After decoding the symbols, candidates can draw a family tree and trace the required relationship.

NIMCET Blood Relations Practice Questions

Practising different formats is important because blood relation questions may require either direct interpretation or multiple steps of reasoning.

Q1. D is son of C and brother of E. E is niece of F. C is the sister of B and aunt of A. The father of B has two kids, a son and a daughter. If A is the son of F, then how F is related to C?

A. Cousin
B. Aunt
C. Sister-in-law
D. Sister

Answer: C (Sister-in-law)

Explanation: Since B's father has only two children (B and C), C has no blood sibling other than B. F is aunt/uncle of E (C's daughter) and parent of A (C's nephew/niece), so F must be related to C through marriage — F is the sister of C's husband. 

Q2. Bharat and Sapna are husband and wife. Rohit and Bharat are brothers. Suresh is the father of Rohit. Sapna's son is Krish. How is Krish related to Suresh?

A. Son
B. Father
C. Uncle
D. Grandson

Answer: D (Grandson)

Explanation: Suresh is the father of Rohit and Bharat (brothers), so Suresh is Bharat's father. Krish is Bharat and Sapna's son, making Krish the grandson of Suresh. 

Q3. Introducing Rukmani, Vijay said, "She is the mother of the son of the only brother of my wife." What is the relation of Rukmani's husband with Vijay?

 A. Brother-in-law
B. Father
C. Father-in-law
D. Son

Answer: A (Brother-in-law)

Explanation: Rukmani is the mother of the son of Vijay's wife's only brother, meaning Rukmani is the wife of Vijay's wife's brother. So Rukmani's husband is Vijay's wife's brother, i.e., Vijay's brother-in-law.

Q4. 'A + B' means 'A is the sister of B'
'A − B' means 'A is the brother of B'.
'A × B' means 'A is the mother of B'.
'A ÷ B' means 'A is the father of B'.
If V + S × Q − P ÷ T + R × U, then how is R related to S?

A. Grandson
B. Daughter
C. Grand-Daughter
D. Maternal grandmother

Answer: C (Grand-Daughter)

Explanation: S is the mother of Q; Q is brother of P (so S is also P's mother); P is father of T; T is sister of R (so R is also P's child); R is mother of U (R is female). Since R is P's child and P is S's child, R is S's grandchild, and being female, R is S's granddaughter. 

Q5. 'A + B' means 'A is the wife of B'.
'A − B' means 'A is the husband of B'.
'A × B' means 'A is the son of B'.
'A ÷ B' means 'A is the mother of B'.
If T + Q × P − U ÷ R ÷ S + V, then how is R related to Q?

 A. Daughter
B. Maternal Grandmother
C. Sister
D. Mother

Answer: C (Sister)

Explanation: Q is son of P; P is husband of U, so U is Q's mother; U is mother of R, making R Q's sibling; R is mother of S, so R is female. Hence R is Q's sister.

How to Solve NIMCET Blood Relation Questions?

A systematic approach can reduce confusion, especially when a question contains several family members.

  1. Identify the question type: Determine whether the question is direct, coded, or paragraph-based.

  2. List the information: Separate each statement and identify the relationship mentioned in it.

  3. Start with the known person: Use the person around whom most of the information is given as the starting point.

  4. Draw a family tree: Connect parents, children, siblings, and spouses using simple lines.

  5. Identify gender: Note whether the people involved are male or female wherever the information is provided.

  6. Track generations: Keep parents, children, and grandparents in their respective generations.

  7. Trace the required relationship: Once the family tree is complete, move from one person to the other to identify their relationship.

  8. Read the options carefully: Compare the relationship you obtained with the given options before selecting the answer.

NIMCET Blood Relations questions mainly test how accurately you can interpret and connect family relationships. A clear understanding of common relations, gender, generations, paternal and maternal sides, and coded symbols can make these questions easier to handle. Regular practice with different question formats, along with the habit of drawing a family tree for complex questions, can help you improve accuracy and avoid common relationship errors.
