Blood Relation Shortcut Trick

  • Next, try to find out middle relation.
  • Finally, find out the relationship between two persons to be identified for this purpose.
Trick 1

General Problem on Blood Relation

Shortcut Approach

  • Read the statement from right to left to develop the relation by using blood relation table.

Example: 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?


(1) B is Brother of A.

My grandfather’s only son = A’s father (grandfather’s only son means only ONE son. No other son and daughter).

(2) 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.

Example: Pointing to a boy Rekha said, “He is the son of my mother-in-law’s only Child”. How is the boy related to Rekha?

Solution: Boy is the Son of Rekha

My mother-in-law’s only child = Rekha’s mother-in-law’s only child = Rekha’s husband.

The boy is the son of the Rekha’s Husband. So obviously Rekha is the mother to that boy and that boy is the Son of Rekha.

Trick 2

Blood relation based on Family Tree

Shortcut Approach

  • Follow the symbols for male (+) and (–) female.
  • Remember the generations and relations.

Example: Q is the brother of C and C is the sister of Q. R and D are brother and sister. R is the son of A while A & C are wife and husband. How is Q related with D?

Trick 3

Coded Blood Relationship

Shortcut Approach

  • The best way to solve blood relation questions, you try and relate every statement to ‘yourself’. The starting name of the statement could be assumed as your name or you.
  • When the statement is very long, it can get confusing. So, break down every statement in the question into sub statements and solve the question.
  • Do not assume the gender of any person in the question just based on the names given in the question.
  • Draw a family tree where people of the same generation are placed at the same level and the entire diagram is in the form of a hierarchy.

Example: If P + Q means P is 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 A in D * B + C / A?

Solution: D is nephew to A

General Method

C / A – C is sister of A.

B + C / A – B is brother-in-law of A (Sister’s husband – brother-in-law)

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

So, D is nephew to A.

Shortcut Method:

By using symbols and generation relations:

So, it is clearly shown that D is nephew to A.
