Preparing for IBPS RRB Blood Relations Questions

Now, let us see what are the things that you should do to solve blood relations questions in the RRB exam.

How Much Practice Should I put in?

It depends on how easy or difficult you find the questions to be. Remember, the questions are inherently easy to solve. If you are finding it difficult to solve, then you only need to practice more and that’s it!

We recommend candidates should put in at least 3 days a week for IBPS Reasoning Preparation. Even if you put 4 hours every day, then that makes it 12 hours every week. That’s more than enough. If blood relations questions seem difficult to you, then try to put in at least 1 hour within that 12 hours just for blood relations. If you are solving blood relations questions every day, then try to solve 8-10 questions. Try to target solving at least 25-30 questions every week. This would help you get the best results in the exam.

How Should I Practice?

At Topprnotes, we believe in studying smart and not just studying hard. The first thing that you need to do is get hold of previous year question papers. Since the test is computer-based, they would be hard to come by. But just keeping searching and you would find some. Previous year question papers give you an idea about the style of the questions that are asked in the examination.

The next thing that you should do is attempt sectional mock tests. They give you the practice that you need. They also help you to build your speed and accuracy.

If you are looking for some extra practice (if you have the time), then you can attempt to solve questions from other exams as well. Blood relation questions are pretty common and they come in exams like IBPS PO, IBPS Clerk, SBI PO, SBI clerk. They even come in Management exams like CAT. So, try to solve a few questions from this exam.

Do I Need to Refer to Some ‘Special’ Books?

Well, there are no ‘special’ books that deal exclusively with solving blood relations questions in IBPS RRB exam. Any good logical reasoning book would be good for the purpose. Add a good test paper book to it, and you are good to go. You can refer to the following books.

Solving IBPS RRB Blood Relations Questions

Alright, now we know what are the questions and how we should prepare for it. Now, let us take a look at the effective methods that you should use to solve the questions. IBPS RRB blood relations questions are infamous for being time-consuming. That’s mostly because candidates don’t follow the right techniques. Let us look at the effective ways of solving the questions that come in the IBPS RRB blood relations questions.

Let us take up the question we used as an example.

Question: In a family, there are six members- A, B, C, D, E and F. A and B are a married couple, A being a male member. D is the only son of C, who is the brother of A. E is the sister of D. B is the daughter-in-law of F, whose husband has died.

What is the relation between F and A?

Solution: A lot of candidates make the mistake of looking at the individual questions and trying to find the answer. This would eat up your time. The best approach is to create a ‘family tree’ based on the given statements. This would allow you to answer all the questions in one go.

To create a family tree, we would need to use some codes:

  • For example, we would use (+) for male and (-) for female.
  • We would keep the younger generation below the older generation

You can use any code that you feel comfortable. We would use this code for explaining. Now, let us look at the steps that you should use to solve the questions

STEP 1: We need to look for a ‘standalone’ positive statement. Such statements would give you positive information and will not be dependent on any other statement. In most cases, it is preferable to start with a parent-child relationship. The third sentence gives such a relationship.

It says “D is the only son of C, who is the brother of A”. So, we have:

STEP 2: Now we are going to look at more information about A, C or D. The second statement and the fourth statement give us that. Based on that information, we have

STEP 3: Now we need to put in the final statement. We have F, whose daughter in law is B. We know she is a female as she had a husband. So, she should be the mother of A. Now, we have:

This single tree would help us solve all the questions. For example, we know that F is the mother of A.

Answer: F is the mother of A

Dos and Don’ts for Solving Blood Relation Questions in IBPS RRB 2018

  • Always use a single set of code.
  • Never mix up the genders.
  • Sometimes you would get questions where relationships would be expressed by symbols. For example ‘+’ for marriage, ‘%’ for parent-child relationship. Write the symbols separately and solve the tree using the method above. Then put the symbol before choosing the answer.
  • Never ever lose your focus.
  • Don’t hurry. One mark is crucial in such exams. If you are attempting it, it’s better to get it right than to leave it and lose the mark.
