Blood Relations Decoded

In this article, a student of NLSIU shares his tried and tested method to crack Blood Relations.

Blood relation questions are the easiest to crack and it is imperative to not only attempt these questions in the competitive examinations but also get them correct. You can’t afford to lose marks in these questions. The reason for this is quite simple, you can be sure of your answer unlike the critical reasoning questions which are quite subjective in nature. In critical reasoning questions, many times it may seem to you that two choices are equally relevant. Sometimes even more than 2 options may seem so! I assure you, you won’t face the same problem with blood relations.

The correct way to go about blood relation questions is to draw a family tree and use some standard signs and practice them over and over. The target is to become so proficient that as soon as you see these relations you can visualize the signs. In order to make your work easier, I will be listing down certain signs which are standard and you can use them while making the family tree. (You may choose to use different signs according to your own convenience).

Listed below are the signs that should preferably be used, remembered and further practiced to save time:

Generally, in CLAT, blood relations problems would involve up to three generations and not more than that. The first and the foremost thing to understand is to place the 3rd generation i.e. grandparents at the top, below that comes the second generation i.e. parents, maternal aunt and uncle, paternal aunt and uncle, brother/sister in laws. Below that comes the first generation i.e. grandson/granddaughter.

To illustrate further:

If we concentrate on these relations, then all other relations can be fit in some way or the other. Say for instance Arjun is the nephew of Kabir, and and it is given that Kabir is the only brother of Aditya, then instead of of being confused about what sign should be used to illustrate the relation between Arjun and Kabir, simply illustrate the relation between Kabir and Aditya and then represent the relation between Aditya and Arjun as has been done below:

An important point to remember, never ever make assumptions about the gender of a person until and unless it is specifically mentioned. For example, if it is given that Karan is the grandparent of Simran, it does not mean that Karan is a male or Simran a female. It can be the other way round as well. You have to look for hints. It is recommended that you should look for pronouns if nothing has been specifically mentioned about the gender of that person. Look whether ‘he’ or ‘she’ has been used and then you can be sure about it. Also it is strongly recommended that you should indicate the gender in a bracket in the family tree itself as has been illustrated above.

Some important relations are provided below. You should remember these relations to solve blood relation problems. Assume every relation given below for a hypothetical X. For e.g. X’s mother’s (or) father’s son- X’s brother:

Mother’s (or) father’s son – Brother

Mother’s (or) Father’s Daughter – Sister

Mother’s brother – Maternal Uncle

Father’s Brother – Paternal uncle

Mother’s (or) Father’s sister – Aunt

Mother’s (or) Father’s father – Grandfather

Mother’s (or) Father’s mother – Grandmother

Son’s wife – Daughter in law

Daughter’s husband – Son in law

Husband’s (or) Wife’s father – Father in law

Husband’s (or) Wife’s mother – Mother in law

Husband’s (or) Wife’s brother – Brother in law

Husband’s (or) Wife’s sister – Sister in law

Sister’s husband – Brother in law

Brother’s (or) Sister’s son – Nephew

Brother’s (or) Sister’s daughter – Niece

Illustrated below are two questions that would further teach you how to draw an appropriate family tree:

1. Pointing to a lady, Rajan said, “She is the daughter of the woman who is the mother of the husband of my mother.” How is the lady related to Rajan?

2. Pointing towards a person in a photograph, Anjali said “He is the only son of the father of my sister’s brother.” How is that person related to Anjali?

Also it is strongly recommended that you use a pencil so that you can make changes to questions which involve multiple parts.

So, practice diligently and intelligently, and get ready to ace this topic in CLAT. ALL THE BEST!
