Assertion Reason Questions
Directions:
In the questions given below, there are two statements marked as Assertion (A) and Reason (R).
Read the statements carefully and choose the correct option:
(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.
Q1. Assertion (A): All even numbers greater than 2 are composite.
Reason (R): Even numbers are always divisible by 2.
Difficulty Level: Medium
Ans. Option (A) is correct.
Explanation: Any even number greater than 2 will have at least three factors (1, 2, and itself), making it composite. The reason clearly explains the assertion.
Q2. Assertion (A): The numbers 7 and 15 are co-prime.
Reason (R): Two numbers are co-prime if both are prime.
Difficulty Level: Hard
Ans. Option (B) is correct.
Explanation: The assertion is true (7 and 15 have no common factor), but the reason is incorrect — two numbers being prime does not guarantee they are co-prime unless they are different and share no common factor. Also, one of them need not be prime for the pair to be co-prime.
Q3. Assertion (A): The number 1 is neither prime nor composite.
Reason (R): A prime number has exactly two distinct positive factors.
Difficulty Level: Hard
Ans. Option (A) is correct.
Explanation: The reason correctly defines a prime number, and since 1 has only one factor (itself), it is neither prime nor composite.
Q4. Assertion (A): The product of two co-prime numbers is always divisible by both numbers.
Reason (R): The least common multiple (LCM) of two co-prime numbers is their product.
Difficulty Level: Medium
Ans. Option (A) is correct.
Explanation: For co-prime numbers, LCM is the product of the numbers, and hence their product is divisible by both. Reason supports the assertion.
Q5. Assertion (A): The prime factorisation of 56 is 2 × 2 × 2 × 7.
Reason (R): A composite number can be expressed as a product of only prime numbers in one unique way (order may differ).
Difficulty Level: Medium
Ans. Option (A) is correct.
Explanation: The assertion is a correct factorisation and the reason is the fundamental theorem of arithmetic, which explains it perfectly.
