Assertion Reason Questions
Q. 1. Assertion (A): The number of edges in a complete graph with 5 vertices is 10.
Reason (R): The number of edges in a complete graph is given by $\frac{n(n-1)}{2}$.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Ans. Option (a) is correct.
Explanation: For $n=5$, the number of edges is
$$
\frac{5(5-1)}{3}=\frac{20}{2}=10 .
$$
Q. 2. Assertion (A): The Koch snowflake becomes smoother with each iteration.
Reason (R): Each iteration adds smaller and smaller triangles to the snowflake.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Ans. Option (d) is correct.
Explanation: The Koch snowflake actually becomes more jagged and detailed with each iteration, not
smoother.
Q. 3. Assertion (A): Stacked triangles follow a triangular number sequence.
Reason (R): In each new shape, one more row of triangles is added compared to the previous shape.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Ans. Option (a) is correct.
Explanation: The growing number of rows in stacked triangles creates a triangular number sequence. This sequence if formed when a new triangle is added in each next row.

What is Assertion Reason Question for Class 6 Maths?
An Assertion-Reason Question for Class 6 Maths consists of two statements:
- Assertion (A) – A factual or conceptual statement.
- Reason (R) – A statement explaining the assertion.
Students must determine whether:
- Both statements are true and R correctly explains A.
- Both are true, but R does not explain A.
- A is true, but R is false.
- A is false, but R is true.
- Both are false.
These questions help in testing conceptual understanding and logical reasoning skills.
Best Ways to Prepare for Assertion Reason Questions
Here are the best ways to prepare for Assertion-Reason Questions in Class 6 Maths:
1. Understand the Concepts Thoroughly
- Focus on fundamental concepts of each chapter.
- Revise definitions, properties, theorems, and their applications.
2. Analyze Cause-and-Effect Relationships
- Identify how one statement logically follows from another.
- Ask yourself: “Why does this happen?”
3. Solve NCERT & Exemplar Problems
- Practice questions from NCERT textbook and Exemplar.
- Look for pattern-based and application-based questions.
4. Read the Statements Carefully
- Pay close attention to keywords like always, never, sometimes, must, can etc.
- Avoid misinterpretation due to tricky wording.
5. Practice Assertion-Reason Questions Regularly
- Solve sample papers, previous year papers, and mock tests.
- Create your own Assertion-Reason questions for better understanding.
6. Learn to Eliminate Wrong Choices
- If R does not logically explain A, eliminate that option.
- If one statement is false, directly eliminate options with both statements true.
Frequently Asked Questions (FAQs)
A1: Assertion-Reason questions consist of two statements—Assertion (A) and Reason (R). The student must analyze their correctness and whether R explains A logically.
A2: Follow these steps:
Check if both A and R are true.
Check if R correctly explains A.
Choose the correct option:(A) Both A and R are true, and R explains A.
(B) Both A and R are true, but R does not explain A.
(C) A is true, but R is false.
(D) A is false, but R is true.
(E) Both are false.
A3: Understand math concepts deeply.
Focus on cause-effect relationships in statements.
Solve NCERT, Exemplar, and mock tests regularly.
Avoid guesswork and read each statement carefully.
A4: They test conceptual understanding rather than memorization.
Help in developing logical thinking and problem-solving skills.
Prepare students for higher-order thinking questions in future exams.
