    If (2, 0) is a solution of the linear equation \[2x+3y=k,\] then the value of k is ____.

    A)  4                                

    B)  6                    

    C)  5                    

    D)         2                    

    Correct Answer: A

    Solution :

    Since, (2, 0) is the solution of \[2x+3y=k.\]So \[(2,0)\]satisfies it. \[\therefore \]\[2\times 2+3\times 0=k\Rightarrow \,\,\,\,k=4\]
