Test: Determinants- Assertion & Reason Type Questions - Question 1
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): If the matrix is singular, then λ = 4.

Reason (R): If A is a singular matrix, then |A|= 0.

Detailed Solution for Test: Determinants- Assertion & Reason Type Questions - Question 1

A matrix is said to be singular if |A| = 0

Hence R is true.

Hence A is true.

R is the correct explanation for A.

Test: Determinants- Assertion & Reason Type Questions - Question 2
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Let A be a 2 × 2 matrix.

Assertion (A): adj (adj A) = A

Reason (R): |adj A|=|A|

Detailed Solution for Test: Determinants- Assertion & Reason Type Questions - Question 2

adj (adj A) = |A|n – 2 A

Here n = 2 ⇒ adj (adj A) = A

Hence A is true.

|adj A| = |A|n – 1 n = 2

⇒ |adj A|=|A|

Hence R is true.

R is not the correct explanation for A.

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): If every element of a third order determinant of value D is multiplied by 5, then the value of the new determinant is 125D.

Reason (R): If k is a scalar and A is an n × n matrix, then |kA|= kn |A|

Detailed Solution for Test: Determinants- Assertion & Reason Type Questions - Question 3

If k is a scalar and A is an n × n matrix, then |kA| = kn|A|.

This is a property of the determinant. Hence R is true.

Using this property, |5?| = 53 ? = 125?

Hence A is true.

R is the correct explanation of A.

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): If then

Reason (R): The inverse of an invertible diagonal matrix is a diagonal matrix.
Detailed Solution for Test: Determinants- Assertion & Reason Type Questions - Question 5

Hence A is true.

A is a diagonal matrix and its inverse is also a diagonal matrix. Hence R is true. But R is not the correct explanation of A.

Test: Determinants- Assertion & Reason Type Questions - Question 6
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Given

Assertion (A): 2A–1 = 9I – A

Reason (R):

Detailed Solution for Test: Determinants- Assertion & Reason Type Questions - Question 6

Hence R is true

∴ 2A-1 =9I - A is true.

R is the correct explanation for A.
