How to Approach

a) Observe alphabets or numbers given in the code keenly.
b) Find the sequence it follows whether it is ascending or descending.
c) Detect the rule in which the alphabets/numbers/words follow.
d) Fill the appropriate letter/number/word in the blank given.

In questions on codes, a word (basic word) is coded in a particular way and the candidates are asked to code other words in the same way. The coding and decoding tests are set up to judge the candidate’s ability to decipher the rule that has been followed to code a particular word/message and break the code to decipher the message.

10. (3)
The alphabets are coded as follows :
D E L H I C A U T
7 3 5 4 1 8 2 9 6
So, in CALICUT,
C is coded as 8, 
A as 2,
L as 5,
I as 1,
U as 9   and
T as 6.
Thus, the code for CALICUT is 8251896.
