    Pick up the correct option to replace the question mark (?). 12, 11, 13, 31, ?, 61.

    A) 38                      

    B)        18

    C) 16    

    D)       15

    E) None of these

    Correct Answer: C

    Solution :

    Explanation Option [c] is correct because digits of numbers get reversed form first to 2nd number, from third to 4th number and from 5th to 6th number. Hence, the 5th number 16 gets reversed to be 61 and to take place as the 6th element of the series. Rest of the options is incorrect because of the correctness of option [c].
