Mixed Letter Coding Decoding Reasoning | Reasoning shortcut | Coding deconding for CLAT 2020
In Mixed Letter Coding Tricks segment of common sense reasoning, secret messages or words have to be decoded. They are coded as per a definite pattern/rule which should be indentified 1st. Then the same is applied to decode another coded word. Under this segment you come across two types of coding, letter coding and number coding. Based on these two types of coding – decoding various types of problems come your way. This chapter makes you familiar with every types of problems base on coding – decoding.

TYPE I (CODING BY LETTER SHIFTING)
Pattern 1: Coding in forward sequence
Example : If ‘GOOD’ is coded as ‘HPPE’, then how will you code ‘BOLD’?
Pattern 2 : Coding in backward sequence.
Example : If ‘NAMI’ is coded as ‘MZLD’, then how will code SAME?
Pattern 3: Coding base on skipped sequence.
Example: If the word ‘FACT’ is coded as ‘IDFW’; then how win you code ‘DEEP’?
Type II (Coding by analogy)
Example: If ‘RPTFA’ stands for ‘BLADE’, how will you code ‘BALE’,
Explanation: Here, ‘BLADE” has been coded as ‘RPTFA’. You will see that all the letters in the word ‘BALE’, which have to be coded, are also there in the word ‘BLADE’. Hence, all that needs to be done is to choose the relevant code letters from the code word ‘RPTFA’. Therefore, B becomes R, A becomes T, L becomes P and E becomes A. Therefore, ‘BALE’ will be coded as ‘RTPA’.

Example : If ‘TEMPERATURE’ is coded as ‘ERUTAREPMET’, then how will you code ‘EDUCATION’ following the same scheme.
EXPLANATION: Here, the word ’TEMPERATURE’ has been reversed. Hence, the code the ‘education’ will be ‘NOITACUDE’.

type iII (coding in fictions language)
In some cases of coding-decoding, fictions language is used to code some words. In such questions, the codes for a group of words is given. In such types of problems, codes for each word can be found by eliminating the common words.
Example: In a certain code language ‘over and above’ is written as ‘da pa ta’ and ‘old and beautiful’ is written as ‘sa na pa’. How is ‘over’ written in that code language?
Explanation: over above = da ta
old beautiful = sa na
Clearly, ‘and’ is common in both and a common code is ‘Pa’.
Code for ‘and’ must be ‘Pa’.
Code for ‘over’ = ‘da’ or ‘ta’.
Code for ‘above’ = ‘da’ or ‘ta’.
Code for ‘old’ = ‘sa’ or ‘na’.
Code for ‘beautiful’ = ‘sa’ or ‘na’
We can’t certainly say what will be exact code for ‘over’. but it is sure that code for ‘over’ must be either ‘da’ or ‘ta’.
TYPE IV (CODING BASED ON NUMBERS)
Pattern 1: When numerical values are given to words.
Example : If in a certain language A is coded as 1, B is coded as 2. C is coded as 3 and so on, then find the code for AEECD.
Pattern 2: When alphabetical code value are given for numbers.
Example : In a certain code 3 is coded as ‘R’, 4 is coded as ‘D’, 5 is coded as ‘n’, 6 is coded as ‘P’ , then find the code for ‘53446’.
TYPE V (MATHEMATICAL OPERATIONS WITH THE POSITION NUMBERS OF LETTERS)
Example: In a certain code, if ‘TALE’ is written as 38, then how will you code ‘CAME’ using the same coding scheme?
Explanation: Look at the numbered alphabet and write down the number corresponding to the letters of the word ‘TALE’.
Practice Questions,
Directions (Q. 35-38): Study the following information and answer the giyen questions :
In a specific code language, ‘hope to see you’ is coded as ‘re so na di’, ‘please come to see the party’ as ‘fi ge na di ke zo’, ‘hope to come’ as ‘di so ge’ and ‘see you the party’ as ‘re fi zo na’.
35. In this code language, ‘please’ is coded as :
a. di b. ke c. ft
d. na e. None of these
36. In this code language, ‘party’ is coded as :
a. Either ‘re’ or ‘fi’ b. Either ‘zo’ or ‘na’
c. Either ‘zo’ or fi’ d. Either ‘zo’ or ‘ge’
e. Either ‘ke’ or fi’
37. In this code language, ‘please see you’ will be coded as:
a. re na Ke b. so re na c. Zo re n e
d. na di Ke e. ke re ge
38. In this code language, code ‘so di re’ means :
a. you see hope b. hope you please
c. hope you come d. the hope to
e. you hope to
39. In a symbolic language, ‘Siberia is a cold place’ is written as ‘a cold is place Siberia’ and ‘water freezes to ice here’ as ‘to ice freezes here water’, then in the same language, covers ten percent of earth’ would be written as :
a. covers earth percent ten of
b. earth of covers percent ten
c. covers earth percent of ten
d. Present of ten earth cover D
e. covers earth ten of percent
40. In a code language, ‘look many books’ is written as ‘sa da na’ and ‘many more days’ as ‘ka pa da’, then in this language, code for ‘books’ is ?
a. sa b. na c. Either sa or na
d. Data not sufficient e. None of these
41. In a symbolic language, ‘how often you come’ is written as ‘ja ha ta na’ and ‘how do you read’ as ‘sa ma ha ta’, then in this language, code for ‘often’ is ?
a. ja b. na c. Either ja or na
d. Data not sufficient e. None of these
