Question

Assertion (A): 7 × 2 + 3 is a composite number.

Reason (R): A composite number has more than two factors.

पर्याय

• Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

• Both, Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (А).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Assertion (A) is false, but Reason (R) is true.

Explanation:

Assertion (A): 7 × 2 + 3 = 14 + 3 = 17

17 is a prime number because it is divisible only by 1 and itself.

So, Assertion (A) is false.

Reason (R): By definition, a composite number is a positive integer greater than 1 that has at least one divisor other than 1 and itself.

So, Reason (R) is true.
