Blood Relations
Blood relations is a topic often covered in verbal ability tests or reasoning sections of exams. It involves understanding the relationships between different individuals based on their familial connections. Here are some common terms and concepts related to blood relations:
1. Parent: A parent is someone who has given birth to or has legal responsibility for a child. There are two types of parents: the father and the mother.
2. Child: A child is the offspring of a parent. Children can be classified as sons or daughters.
3. Sibling: Siblings are individuals who share at least one parent. They can be classified as brothers or sisters.
4. Grandparent: A grandparent is the parent of someone's parent. There are two types of grandparents: paternal and maternal. Paternal grandparents are the parents of one's father, while maternal grandparents are the parents of one's mother.
5. Grandchild: A grandchild is the child of someone's child. Like grandparents, grandchildren can be classified as paternal or maternal based on the parent's side.
6. Aunt: An aunt is the sister of someone's parent. Like grandparents, there are paternal aunts (the father's sister) and maternal aunts (the mother's sister).
7. Uncle: An uncle is the brother of someone's parent. Similar to aunts, uncles can be paternal (the father's brother) or maternal (the mother's brother).
8. Cousin: A cousin is the child of one's aunt or uncle. Cousins can be classified as paternal or maternal based on their parent's side.
9. Niece: A niece is the daughter of someone's sibling.
10. Nephew: A nephew is the son of someone's sibling.
These are some of the common terms used to describe familial relationships.

Example 6: Five people—John, Mary, Peter, Sarah, and David—are part of a family. The following information is known:
- John is Peter's father.
- Mary is David's sister.
- Sarah is John's wife.
- Peter and David are brothers.
Question: What is the relationship between Sarah and David?
Solution: To solve this question, let's analyse the given information:
- John is Peter's father. This tells us that John is the father of Peter.
- Mary is David's sister. This indicates that Mary is the sister of David.
- Sarah is John's wife. This states that Sarah is married to John.
- Peter and David are brothers. This information confirms that Peter and David are siblings.
Based on this information, we can determine the relationship between Sarah and David. Since John is Peter's father and Sarah is John's wife, Sarah is Peter's mother. As Peter and David are brothers, Sarah is also David's mother. Therefore, Sarah's relationship with David is motherly.
These examples illustrate how blood relation questions present a series of familial relationships, and you need to determine the relationship between two individuals based on the given information. The key is to analyse the information and use logical reasoning to arrive at the correct answer.
