Blood Relations – CA Foundation Logical Reasoning Questions
Definition
Those persons who are related to another persons by birth rather than by marriage are called in Blood Relation.
Let’s start right from basic and see what are the different blood relations in a family, which we should know to understand the logical reasoning in blood relation questions.
Remember the relations as given below:
(i) Children of Same parents → Siblings
One’s Husband or Wife → Spouse
Relatives on Mother’s Side → Maternal
Relatives on Father’s Side → Paternal
(ii) Father’s Father → Paternal Grandfather
Father’s Mother → Paternal Grandmother
Mother’s Father → Maternal Grandfather Mother’s
Mother → Maternal Grandmother
Father’s Brother → Paternal Uncle
Father’s Sister → Paternal Aunt
Mother’s Brother → Maternal Uncle
Mother’s Sister → Maternal Aunt
Uncle or Aunt’s Child → Cousin
Sibling’s Son → Nephew
Sibling’s Daughter → Niece
Son or Daughter’s Child → Grandchild
(iii) Relations
- Grandfather’s son → Father or Uncle
- Grandmother’s son → Father or Uncle
- Grandfather’s only son → Father
- Grandmother’s only son → Father
- Mother’s or father’s mother → Grandmother
- Son’s Wife → Daughter-in-Law
- Daughter’s husband → Son-in-Law
- Husband’s or wife’s sister → Sister-in-Law
- Brother’s son → Nephew
- Brother’s daughter→Niece
- Uncle or aunt’s son or daughter → Cousin
- Sister’s husband → Brother-in-Law
- Brother’s wife→Sister-in-Law
- Grandson’s or granddaughter’s daughter → Great Grand Daughter
Family Tree – Generally, the construction of the family tree is considered to be the most appropriate way of solving blood relation questions in Logical reasoning. So we start with representing each by gender by a particular sign. Keep these instructions in mind.
(i) Use “ + ” sign for male & “ – ” sign for female. As A is male → A+; B is female → B
(ii) A is the brother of B → A+ ← bro. → B [Here gender of B is not given, So do not show gender of B ]
(iii) A is the sister of B → A– ← Sis. —»B [ B may be male or female ]
(iv) A is the wife of B → A– ⇔ B +
In this case we know the gender of both A and B. We are using a double-sided arrow here to show that the two individuals are married to each other.
(v) We start by plotting the tree on different levels, where each level represents a generation in blood relation questions.
A is the son of
[We cannot determine the gender of B since B can be either of the parent, mother or father]
(vi) A is the mother of
[We cannot determine the gender of B since B can be either of the child, son or daughter]
(vii) A is the grandfather of
[We cannot determine the gender of B since B can be either of the grandchild, grandson or granddaughter.]
The 2 arrows represent that they are 2 generations away i.e. gap.
Let us try to understand through examples.
Example 1:
P is Q’s daughter, Q is R’s mother. S is R’s brother. How is S related to P?
(a) Father
