CBSE Class 9 Maths Assertion & Reasoning Questions: The CBSE Class 9 Maths question paper for the Board Exam 2025 will include assertion and reasoning questions. These questions present two statements: an assertion (a statement of fact) and a reason (an explanation for the assertion). Students must select the correct outcome from four options based on the relationship between these statements.
Solving assertion and reasoning questions demands careful analysis and logical thinking, as the statements can be confusing and lead to errors. Consistent practice and a clear understanding of concepts are essential for mastering this skill. The provided assertion and reasoning questions, prepared by subject experts, are valuable for last-minute revision and concept reinforcement before the exam.

CBSE Class 9 Maths Assertion Reason Questions with Answers
Below is given the set of most important Assertion and Reasoning Questions with answers for CBSE Class 9 Maths Exam 2025 preparation:
DIRECTION: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
A). Both assertion(A) and reason(R) are true and reason (R) is the correct explanation of assertion (A).
B). Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
C) .Assertion (A) is true but reason (R) is false.
D). Assertion (A) is false but reason (R) is true.
1. Assertion: Rational number lying between two rational numbers x and y is (x+y)/2.
Reason: There is one rational number lying between any two rational numbers.
2. Assertion: 5 is a rational number.
Reason: The square roots of all positive integers are irrationals.
3. Assertion : 2x-1 is the linear polynomial.
Reason : A polynomial of degree 1 is called linear polynomial.
