IBPS – Blood relations Study materials:

Blood relations are a very important topic of any Aptitude Test. Such questions may be asked directly or may be given in the form of coded blood relations or data sufficiency questions. Some of the tricks to solve Blood relations questions are as follows:

1. Apply the question to yourself

This is the best way to solve blood relation questions. Here, you try and relate every statement to yourself. The starting name of the statement could be assumed as your name or you. Let us apply this technique to solve a question

She is Mohit’s brother’s mother’s sister

Here Assume that Mohit = you

Your brother’s mother = your mother

Your Mothers sister = Maternal Aunt

Answer = Maternal aunt

2. Break the question into very small parts

When the statement is very long, it can get confusing. So break down every statement in the question into sub statements and solve the question. For Example:

He is Preetiya’s brother’s aunt’s husband’s son

Suppose you are Preetiya


Your brother

Brothers aunt = your aunt

Your aunt’s husband= your uncle

Your uncle’s son = your cousin

Answer = cousin

3. Do not assume the gender

Do not assume the gender of any person in the question just based on the names given in the question.

For example:

Hari is the brother of Mukash. Mukash is the brother of Vinoth. How is Vinoth related to Hari?

In this by using the explanation above:

Hari(m) ➜ Mukash(m) ➜Vinoth(x)

In the given question Vinoth’s gender is not given. Hence, Vinoth can be brother or sister of Hari. Please take into consideration that the gender of a person can’t be decided based on the name of the person. The given information should significantly support the gender of the person.

4. Draw clear diagrams as you solve

An easy trick to solve such questions with 100% accuracy is to draw a family tries where people of the same generation are placed at the same level and the entire diagram is in the form of a hierarchy.

Coded Blood Relations Question:

In this category of questions, relations depicted by codes and symbols, for example, +, -, /, *. We must analyze the required relation based on the code given.

If A + B means A is the husband of B

A / B means A is the sister of B

A * B means A is the son of B.

How is F related to P in F*B+C/P?

Solution: Start solving from left to right or right to left. We have solved this from right to left.

Clearly mention the gender of each person.

Answer: F is the nephew of P.

Important points to remember:

Concentrate on points that give maximum definite information.

Read the questions carefully and try identifying the persons between whom the relationship is to be established. Possibly put yourself in a given character so that it becomes easy for you to understand.

Whilst concluding the relationship between two people be careful about the gender of the person being talked about as it is possible to commit a mistake by assuming the gender of the person which is not given in the data or which can’t be extracted from the data/information given.

Some of the unsolved questions for practice:
