    Question

    If A equals open square brackets table row 1 0 1 row 0 1 1 row 1 0 0 end table close square brackets, then A is

    1. Symmetric    
    2. Skew-symmetric    
    3. Non-singular    
    4. Singular    

    The correct answer is: Non-singular

      capital delta equals open square brackets table row 1 0 1 row 0 1 1 row 1 0 0 end table close square brackets equals negative 1 not equal to 0, hence matrix is non-singular.
