    For any integer n, what is the HCF of integers \[m=2n+1\] and \[k=9n+4?\]

    A) 3

    B)  1        

    C)  2

    D)  4

    Correct Answer: B

    Solution :

    Since, \[m=2n+1\]is an odd integer, so it may be factors 1 or 3. And \[k=9n+4\] its factors may be 1, 2 and 4. Hence, HCF of (m, k) is 1.
