Boost Your Speed in Blood Relations Questions for RBI Grade B Exam

Blood Relations is an important part of the Reasoning Ability section in the RBI Grade B Phase 1 exam. It tests the candidates’ ability to understand and process relationships based on the given data. This topic is common in most Reasoning sections and very scoring. But only if you can solve it quickly and correctly. Many students confuse themselves with words like maternal uncle or daughter-in-law. Especially when complicated family trees are involved. This blog will guide you with smart and effective tips to solve Blood Relations questions fast and accurately. You’ll also find some sample questions with solutions to help you strengthen your preparation and boost your speed in this key topic.

Tips to Solve Blood Relations Questions Quickly

Before we dive into the sample questions, let’s take a look at the best tips to master Blood Relations questions:

1. Always Start by Drawing a Family Tree

Don’t try to solve these questions in your head. It’s easy to get lost. Use symbols or letters to represent family members and link them logically.

Here are some tips:

• Use M for Male and F for Female.
• Use arrows or lines to show relationships (→ for child, ↑ for parent).
• Keep generations clearly separated.
• Avoid rewriting the entire question—just map it out.
• It saves time and reduces confusion.

2. Pay Close Attention to Gender Clues

Many questions hinge on gender-specific roles like brother, sister, aunt, etc. To answer such questions, never assume gender and find keywords.

Here’s how to do it:

• Look for pronouns like he, she, his, her.
• Confirm gender with context.
• If gender isn’t given, keep it open while solving.
• Incorrect gender assumptions cause errors.
• Highlight gender clues while reading the question.

3. Use Reverse Logic When Required

Sometimes, it’s easier to start from the end of the statement. So, try solving it backwards if the forward way seems confusing.

Let’s break it down:

• Start with the last part of the statement.
• Work backward to the starting point.
• It clears the picture in complex, nested statements.
• This trick works especially well with “How is A related to B?” type questions.
• Reverse solving helps in eliminating options faster too.

4. Practice Different Patterns Regularly

Blood Relations questions come in multiple formats. Hence, you need to practice all common types to increase confidence and accuracy.

Use this simple process:

• Statement-based questions.
• Puzzle-style or coded relationships.
• Mixed with directions or seating arrangement.
• Solve previous year questions regularly.
• Track new patterns in recent exams.

5. Time Yourself During Practice

Speed matters a lot in the RBI Grade B exam. So, cultivate a habit of solving each question in under 1 minute.

Here’s the way to go about it:

• Use a timer while solving practice sets.
• Bit by bit, increase your solving speed with tougher questions.
• Note your mistakes and revisit confusing types.
• Try sectional tests focused only on Blood Relations.
• Recreate real exam conditions during practice.

Sample Blood Relations Questions for Practice

Directions [1-2]: Answer the questions based on the information given below:

In a certain language,

‘A $ B’ means ‘B is wife to A’,

‘A # B’ means ‘A is daughter of B’,

‘A @ B’ means ‘B is son of A’,

‘A % B’ means ‘A is mother of B’,

‘A & B’ means ‘B is sister of A’,

‘A © B’ means ‘A is husband of B’.

Question 1: If “P $ Q & R # S © T & U @ O © L % N” is definitely true, then how is R related to N’s father’s mother?

A) Aunt

B) Mother-in-law

C) Niece

D) Daughter-in-law

E) Cannot be determined

Solution:

Given code: P $ Q & R # S © T & U @ O © L % N

After decoding the code, we get

P is husband of Q, who is sister of R. S is father of R and husband of T. U is sister of T. O is son of U. L is wife of O, who is father of N.

We draw the following family tree:

Here, N’s father’s mother is U.

R is the niece of U.

Hence, option c.

Question 2: If “C © E @ G & D % F # H @ J $ K” is definitely true, then how is J’s spouse related to C’s only daughter?

A) Granddaughter

B) Grandson

C) Daughter-in-law

D) Nephew

E) Cannot be determined

Solution:

Given code:

After decoding the code, we get

C is husband of E. G and D are children of E. D is wife to H. H is father of F and J. J is husband of K.

We draw the following family tree:

J’s spouse is K and C’s only daughter is D.

K is daughter-in-law of D.

Hence, option c.

Directions [3-5]: Answer the questions based on the information given below:

A % B means A is married to B

A # B means A is father of B

A & B means A is sister of B

A $ B means A is son of B

A β B means A is daughter-in-law of B

A ≤ B means A is father-in-law of B

A π B means A is maternal uncle of B

A ≠ B means A is mother of B

A µ B means A is niece of B

H % K, K $ L, L β P, P π V, G & V, N # V, F ≤ H, N % X

Common solution:

After decoding the codes, we get:

H % K means H is married to K.

K $ L means K is son of L.

L β P means L is daughter-in-law of P

P π V means P is maternal uncle of V

G & V means G is sister of V

N # V means N is father of V

F ≤ H means F is father-in-law of H

N % X means N is married to X.

The blood relation tree we can draw using the above information is:

Question 3: If ‘V µ Q & P’, the how many female members are there in the family (including Q)?

A) Three

B) Five

C) Four

D) Six

E) Either ‘b’ or ‘d’

Solution:

There are six female members in the family (including Q).

E) All I, II and III

Solution:

Statements:

I. G is daughter-in-law of N – False (G is daughter of N)

II. K is grandson of P – True

III. Gender of H and G is same – True

Only II and III are true.

Hence, option b.

Question 5: If ‘V ≠ E & L $ J’, then how is how is G related to L?

A) Mother-in-law

B) Paternal aunt

C) Maternal aunt

D) Grandmother

E) None of the above

Solution:

After decoding the codes, we get:

V ≠ E means V is mother of E

E & L means E is sister of L

L $ J means L is son of J

Therefore, the family tree we get after adding the above information:

So, G is maternal aunt of L.

Hence, option c.
