JEE MainMathematicsMatrices and DeterminantsMCQ+4 / −1
Consider the system of linear equations x+y+z=5,x+2y+λ2z=9,x+3y+λz=μx+y+z=5, x+2 y+\lambda^2 z=9, x+3 y+\lambda z=\mux+y+z=5,x+2y+λ2z=9,x+3y+λz=μ, where λ,μ∈R\lambda, \mu \in \mathbb{R}λ,μ∈R. Then, which of the following statement is NOT correct?
  1. A
    System is consistent if λeq1\lambda eq 1λeq1 and μ=13\mu=13μ=13
  2. B
    System is inconsistent if λ=1\lambda=1λ=1 and μeq13\mu eq 13μeq13
  3. C
    System has unique solution if λeq1\lambda eq 1λeq1 and μeq13\mu eq 13μeq13
  4. D
    System has infinite number of solutions if λ=1\lambda=1λ=1 and μ=13\mu=13μ=13
