Question

If A is a singular matrix, then adj A is :

  1. singular    
  2. non-singular    
  3. symmetric    
  4. not defined    

The correct answer is: singular


    If A is a singular matrix rightwards double arrow It means |A| = O
    Then |adj. A| = |A|n–1
    so (adj. A) is also singular matrix
