Reasoning_Blood Relation
Introduction
- Any relation in the world which either by birth or by marriage is called a Blood Relation.
- Ex: Any relation by birth will be mother, father, son, daughter, etc. and any relation by marriage will be father-in-law, mother-in-law, etc.
- There also are a few things which need to be kept in mind while solving the blood relation questions. Given below are few such important points :
- You cannot assume the gender of the person based on the name
- If the statement says X is the son of Y, the gender of Y cannot be determined unless mentioned in the question
- In puzzle based questions, a web of relations can be formed, so do not solve such questions in a haste
- These questions are scoring and easy to solve, so do not panic if the question seems lengthy
- In case of coding-decoding blood relation, use a pictorial description to solve the question. This will make the symbols and relation more clear.
Family Tree
The following points help in drawing a family tree.
- All the female members of the family are represented by a circle. The name of the person is written inside the circle for convenience.
- All the male members of the family are represented by a square. The name of the person is written inside the square for convenience.
- The relation between two members of the family is shown by connecting a double-headed arrow.
- The spouse relation is represented by the two ends of a double-headed arrow.
- All the family members of the upper generation are represented above in the family tree. Ex: father, mother, uncle, aunt etc. The logic can be extended by representing the grandparents above the parents in the family tree. Ex: grandfather and grandmother.
- All the family members of the same generation are represented in the middle of the family tree. Ex: brothers, Sisters, cousins, wife, husband, etc.
- All the family members of the next generation are represented below in the family tree. Ex: Daughter, son, niece, nephew.
- Akash and Arjun are brothers and Anne is the wife of Arjun.
- Myra is the daughter of Arjun and Anne.
- Veena is the mother of Akash and She has three brothers, Vishnu, Ravi and Guru.
- Lakshmi Narayan is the father of Arjun and the son of Krishna Rao and Radha.
- Narayan and Shakuntala are husband and wife and are the parents of Veena.
