    If 34N is divisible by 11, then what is the value of N?

    A)  1                    

    B)  3

    C)  4                    

    D)  9

    Correct Answer: A

    Solution :

    [c] A number is divisible by 11, if difference of the sum of the digits at the even places and sum of digits at odd places is either 0 (zero) or a multiple of 11. Now, \[(3+N)-\,4=0\] \[3+N-\,4=0\] \[N-\,1=0\] \[\therefore \,\,N=1\]
