Statement-1 (Assertion and Statement- 2 (Reason)
Each of these questions also has four alternative
choices, only one of which is the correct answer. You
have to select the correct choice as given below.
Statement- 1 If A, B, C are matrices such that
`abs(A_(3xx3))=3, abs(B_(3xx3))= -1 and abs(C_(2xx2)) = 2, abs(2 ABC) = - 12.`
Statement - 2 For matrices A, B, C of the same order
`abs(ABC) = abs(A) abs(B) abs(C).`

A

Statement- is true, Statement -2 is true, Statement-2
is a correct explanation for Statement-1

B

Statement-1 is true, Statement-2 is true, Sttatement - 2
is not a correct explanation for Stamtement-1

C

Statement 1 is true, Statement - 2 is false

D

Statement-1 is false, Statement-2 is true

Text Solution

Verified by Experts

The correct Answer is:
D
ABC is not defined, as order of A, B and C are such that they
are not conformable for multiplication.
Hence, Statement-1 is false and Statement -2 is true.
