Question

if a machine is coded as 19-7-9-14-15-20-11 so what is danger coded as?


Solution

Sol. Clearly, every letter is assigned is 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) i.e. 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).
