Statement -1 (Assertion) and Statement - 2 (Reason)
Each of these examples 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 A is singular matrox pf order `nxxn,`
then adj A is singular.
Statement -2 `abs(adj A) = abs(A)^(n-1)`

A

Statement - 1 is true, Statement - 2 is true , Statement - 2
is correct explanaction for Statement -1

B

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

C

Statement-1 is true, Statement-2 is false

D

Statement-1 is false, Statement-2 is ttrue

Text Solution

Verified by Experts

The correct Answer is:
D
If A is non-singular matrix of order `nxxn,` then
`abs(adj A) = abs(A)^(n-1)`
Hence, Statement- 1 is false and Stement- 2 is true.
