CBSE 2026 Board Exam Set 1 (Code 30/1/1)
CBSE_BOARD_PYQ_2026_30_1_1
Grade 10
Question:
[Section A]
Assertion (A): The HCF of two numbers is 5 and their LCM is 200, then the product of the two numbers is 1000. Reason (R): For any two positive integers $a$ and $b$, $\text{HCF}(a, b) \times \text{LCM}(a, b) = a \times b$.
(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.
Step-by-Step Solution
Key Concept: Product formula for HCF and LCM.
Sol. (A) Both A and R are true and R is correct explanation of A. [1.0 Mark]
Correct Answer:(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
