Blood Relations

Blood Relation questions are based on mingled information given about different family members as in a puzzle. Right from first point onward the information should be put down in a symbolic manner which when combined in the end becomes the family chart.

Before delving further into approach of solving questions, it is important to understand what is meant by different relations –

Another child of own parents i.e. brother or sister
Male sibling (shall never mean cousin)
Female sibling (shall never mean cousin)
Father's Brother
Paternal Uncle
Father's Sister
Paternal Aunt
Father's Father
Paternal Grand Father
Father's Mother
Paternal Grand Mother
Mother's Brother
Maternal Uncle
Mother's Sister
Maternal Aunt
Mother's Father
Maternal Grand Father
Mother's Mother
Maternal Grand Mother
Sister's Husband
Sister's Daughter
Sister's Son
Brother's Wife
Brother's Daughter
Brother's Son
Uncle's Wife
Uncle's Daughter
Uncle's Son
Aunt's Husband
Aunt's Daughter
Aunt's Son
Wife's Father
Wife's Mother
Wife's Brother
Wife's Sister
Husband's Father
Husband's Mother
Husband's Brother
Husband's Sister
Son's Wife
Daughter's Husband
Daughter's Daughter
Grand Daughter
Daughter's Son
Grand Son
Son's Daughter
Grand Daughter
Son's Son
Grand Son

While solving questions on this chapter it is advised to make family charts with different levels to designate different generations and also write the relation that a person is fulfilling to denote her/his gender as illustrated in #1.

Another important point to remember is that one should not make biases about name/gender as any name could belong to any gender. (refer #2).

While plotting the family chart one should remember that in a sentence if “who” is written it refers to the previous person discussed in the passage. On the other hand if “and” is added to “she” or “he” then it refers to the first person mentioned in that sentence. (refer #2)

#1. A is the brother of B, who’s mother E is married to D, who’s only daughter’s daughter is F. If C is the paternal aunt of A’s son G, then how is B related to G’s only cousin?

a) Aunt   b) Uncle   c) Cousin   d) Can’t be determined

The above information can be broken into points and the family chart shall evolve as follows:

As E & D have only one daughter, it has to be C and B will be uncle to G’s cousin F. Hence b)

#2. Anil and Bhaskar were best friends who later went on to become brothers-in-law. Bhaskar is the only child of his parents who are also friends of Anil’s parents Chirag and Deepa, who have two children Anil and Ekta. How is Bhaskar’s daughter Fagun related to Anil, and how is Chirag related to her?

a) Uncle and Granddaughter   b) Uncle and Grandfather   c) Niece and Grandfather   d) Niece and Grandfather/Grandmother

Here the following chart can be made –

There are only two ways for Anil and Bhaskar being brothers-in-law – i) Anil marries Bhaskar’s sister (which is not possible as Bhaskar is the lone child of his parents) ii) Bhaskar marries Anil’s sister [this has to be true as i) cannot happen]. This also implies that Ekta must be female as Anil has only one sibling. However genders of Chirag and Deepa could not be established and either of them could be father/mother of Anil & Ekta.

Hence Bhaskar and Ekta’s daughter Fagun is niece of Anil while Chirag could be either Grandfather or Grandmother of Fagun. Hence d)
