If a system of three linear equations in three unknowns, which is in the matrix equation form of \(A X=D\), is inconsistent, then \(\frac{\text { rank of } A}{\text { rank of } A D}\) is

  1. A less than one
  2. B greater than or equal to one
  3. C one
  4. D greater than one
Verified Solution

Answer & Solution

Correct Answer

(A) less than one

Step-by-step Solution

Detailed explanation

We have given a system of linear equations with the three unknowns. Here, equations are in the matrix form \(A X=D\) such that the system is inconsistent. \(\therefore \quad\) Rank of Augmented matrix AD \(>\) Rank of coefficient matrix A Rank of AD > Rank of A…
