    C) 10 - 7 - 20 - 13 - 11 - 24  

    D) 13 - 7 - 20 - 10 - 11 ? 25

    E) None of these

    Correct Answer: C

    Solution :

    Explanation Option [c] is correct. Clearly, every letter is assigned a numerical code obtained by adding 6 to the numeral denoting the position of that letter in the English alphabet. Thus, A is coded as (1+6) i.e. 7, B as (2+6) i.e. 8, C as (3+6) i.e. 9,....., M as (13+6) Le 19,....., Z as (26+6) i.e. 32. Since, D, A, N, G, E, R are 4th, 1st, 14th, 7th, 5th and 18th letters in the English alphabet, so their respective codes are (4+6), (1+6), (14+6), (7+6), (5+6), (18+6) i.e. 10, 7, 20, 13, 11, 24. So, the code for DANGER is 10 - 7 - 20 - 13 - 11 - 24, Hence, the answer is [c].
