    If \[a=4b+26\], and 'b' is a positive integer, which of the following does not divide 'a'?

    A)  \[2\]                                    

    B)  \[5\]   

    C)  \[4\]                    

    D)         \[6\]                    

    Correct Answer: C

    Solution :

    \[a=4b+26\] Consider \[b=1\]. Then \[a=4(1)+26=30,\] which is divisible by 2, 5 and 6, but not 4. Hence option (C) is the answer.
