Important Coding-Decoding Topics for Bank Exam

Topics	Explanation
Basic Points for Alphabets/ Numbers and Words Coding-Decoding	Positions of alphabets (A=1, B=2, C=3, D=4,...Z=26) Opposite positions will be like (A=26, B=25, C=24, D=23,... Z=1) Opposite of each alphabet like (A to Z, B to Y, C to X, D to W, and so on)
Letter Coding	By following a specific rule, in this coding, the alphabets of a word are replaced by certain other alphabets. For example, 'DONKEY' can be written as 'ENOJFX' by following one step forward and one step backward letters of code. Likewise, 'HORSE' can be written as 'INSRF' by following the same rule.
Substitution	Here names or words are substituted with different names or words. For example, if ‘cat’ is known as ‘dog’, ‘dog’ is known as ‘tiger’, ‘tiger’ is known as ‘lion’. What will be the name of the ‘national animal’? Here, as ‘tiger’ is coded as ‘lion’ so, the answer will be ‘lion’ instead of ‘tiger’.
Mixed Letter Coding	Here you have to find out a particular coded word with reference to three-four messages of the coded language. For example, If 'tpw lkp otr' stands for 'neat and tidy' 'inm sen tpw ' stands for 'small but neat', and 'grh sen hwt' stands for 'good but erratic', what would 'but' stand for? The answer will be 'sen', as in the 2nd and 3rd statement the common code word is 'sen and but.'
Mixed Number Coding	Here you have to find out the numbers in relation to phrases. For example, if '57' means 'which category' and '985' means 'class and category'. What is the code for 'category'? The answer will be 5, because the common code digit is '3' and the common word is 'category'.
