Assertion (A) & Reason (B) MCQ

Question 11 Mark

Consists of two statements, namely, Assertion (A) and Reason (R). For selecting the correct answer, use the following code:

Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).
Both Assertion (A) and Reason (R) are true but Reason is not a correct explanation of Assertion (A).
Assertion (A) is true and Reason (R) is false.
Assertion (A) is false and Reason (R) is true.

Assertion (A)	Reason (R)
e is an irrational number.	$\pi$ is an irrational number.

The correct answer is: (a), (b), (c), (d).

Answer

Both Assertion (A) and Reason (R) are true but Reason is not a correct explanation of Assertion (A).
Solution:
e and $\pi$ both are irratinoal numbers
So, both Assertion (A) and Reason (R) are true
But the Reason (R) is not a correct explanation of Assertion (A), so (b) holds.

Question 361 Mark

Consists of two statements, namely, Assertion (A) and Reason (R). For selecting the correct answer, use the following code:

Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).
Both Assertion (A) and Reason (R) are true but Reason is not a correct explanation of Assertion (A).
Assertion (A) is true and Reason (R) is false.
Assertion (A) is false and Reason (R) is true.

Assertion (A)	Reason (R)
$\sqrt{3}$ is an irrational number.	Square root a positive integer which is not a perfect square is an irrational number.

The correct answer is: (a), (b), (c), (d).

Answer

Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).
Solution:
We know that if $\sqrt{\text{x}}$ is an irratinal number, it means x is not a perfect square.
Thus, Assertion (A) is true
Since Reason (R) gives Assertion (A), so (a) holds.
