RRB Group D Exam 04 August 2026 All Shift Reasoning Exam Review by Prashant Sir

The Reasoning section in all shifts of the RRB Group D Exam on 4 August 2026 tested candidates on logical thinking, analytical ability, and problem-solving skills. Most questions were concept-based and could be solved quickly with proper practice.

The paper included a healthy mix of easy, moderate, and a few lengthy questions, especially from Seating Arrangement and Puzzle topics.

Important Topics Asked in the 4 August RRB Group D Reasoning Paper

The most frequently asked Reasoning topics were:

• Coding-Decoding

• Alphabet Test

• Word Formation

• Seating Arrangement

• Box Puzzle

• Blood Relations

• Distance & Direction

• Ranking Test

• Mathematical Operations

• Inequality

• Syllogism

• Venn Diagram

Coding-Decoding

Coding-Decoding remained one of the most important topics in the exam.

Opposite Letter Coding

Candidates were asked to decode words using the opposite alphabet rule, where every letter is replaced by its opposite alphabetical letter (A↔Z, B↔Y, C↔X, etc.).

For example:

• R → I

• A → Z

• I → R

• L → O

• W → D

• A → Z

• Y → B

Questions based on this concept were straightforward for students familiar with opposite letter pairs.

Mixed Letter Shifting

Another Coding-Decoding question involved different alphabetical shifts.

Example:

NKHN → SPMH

Candidates had to identify the shifting pattern before decoding the complete word. Prashant Sir advised solving the entire code carefully instead of relying only on the first few letters, as the options were intentionally similar.

Alphabet-Based Word Transformation

A question based on the word SCIENCE tested alphabetical transformations.

The rule was:

• Replace every vowel with its previous alphabet.

• Replace every consonant with its next alphabet.

After transformation, students had to identify the letter appearing most frequently. Such questions mainly tested observation skills and knowledge of alphabetical order.

Seating Arrangement Questions

Seating Arrangement remained one of the most important sections.

Questions included:

• Linear Seating Arrangement

• Circular Seating Arrangement

Candidates solved arrangements using fixed-position clues before applying relative position statements.

Important tips shared by Prashant Sir:

• Start with definite clues.

• Avoid solving the entire arrangement if the question can be answered earlier.

• For centre-facing circular arrangements:

• Right = Clockwise

• Left = Anti-clockwise

Puzzle Questions

The paper also included Box Stacking puzzles.

Students arranged boxes vertically using clues like:

• Immediate above/below

• Number of boxes between two boxes

• Topmost and bottom-most positions

These questions were moderate in difficulty but became easy after placing the fixed positions first.

Blood Relation Questions

Blood Relation questions appeared in both direct and coded formats.

Topics included:

• Mother-in-law

• Brother-in-law

• Parent-child relationships

• Family tree construction

Prashant Sir recommended drawing a family tree instead of solving mentally, as it reduces mistakes and saves time.

Ranking Test

A ranking question asked candidates to calculate the position of a person from the opposite end.

The standard formula used was:

Total Persons = Left Rank + Right Rank – 1

Candidates familiar with this formula could solve the question quickly.

Distance and Direction

Distance & Direction continued to be one of the most scoring chapters.

Questions tested:

• Direction identification

• Relative positions

• Minimum distance

One question required finding the shortest distance after multiple turns using the Pythagorean Theorem.

Example:

• Horizontal displacement = 5 km

• Vertical displacement = 12 km

Minimum Distance = √(5² + 12²)

= √169

= 13 km

Prashant Sir also reminded students that "minimum distance" always refers to the straight-line (aerial) distance.

Inequality

Candidates solved inequality questions by checking whether conclusions logically followed the given statements.

Important concept:

If the symbols face away from each other (for example, X < Y > Z), no definite relationship can be established between X and Z unless additional information is provided.

Mathematical Operations

Two questions were based on Mathematical Operations.

Topics included:

• Symbol replacement

• Interchanging mathematical operators

• BODMAS application

Students first replaced symbols with actual operators and then applied the correct order of operations to obtain the final answer.

Syllogism

The paper included standard Syllogism questions involving:

• Positive statements

• Negative statements

• Logical conclusions

A key concept highlighted during the review was that combining a positive statement with a negative statement generally results in a valid negative conclusion rather than a positive one.

Venn Diagram

One Venn Diagram question asked candidates to identify individuals belonging to two groups while excluding a third group.

The question was simple and could be solved quickly by carefully identifying the overlapping regions.

Prashant Sir's Exam Strategy

According to Prashant Sir, candidates should focus on accuracy before attempting speed.

His key recommendations include:

• Begin with easy and direct questions.

• Solve Seating Arrangement and Puzzle questions only after identifying definite clues.

• Skip lengthy questions initially and revisit them later.

• Follow BODMAS strictly in Mathematical Operations.

• Draw family trees for Blood Relation questions.

• Practice Distance & Direction regularly, as it consistently appears in RRB exams.

• Take mock tests to improve speed and time management before the final examination.
