Coding Decoding (Old Pattern ) Tricks & Tips


 

GovernmentAdda has uploaded the coding and decoding shortcut methods, Tricks & Rules and Questions with Answers here. Candidates can check and go through it. Coding and decoding tips are very useful to those who are preparing for the attending the bank exam IBPS, SBI, LIC AAO, UPSC, IAS, CAT, XAT, MAT, SSC, GATE, and other competitive exams. We have also published the Solved examples for the coding and decoding aptitude.

 

Coding-decoding is one of the most important topic in reasoning section of any competitive exams. We can expect 5-6 questions from this section.

Types of Coding-Decoding:

  • Letter Coding
  • Number Coding
  • Symbol Coding
  • Number-Letter mixed coding

 

  • LETTER CODING:

Coding based on alphabets or words, given on some special pattern which you have to look and analyze and answer according to it. In this first you have to look the both letter code and notice the position of alphabets in the letter, and answer the common pattern available in the option.

Order List of Alphabets:

Example:

If “EXAM” is coded as “FYBN”, how is “RESULT” coded in the same language?

Solution:-

  • NUMBER CODING:

Number Coding are based on numbers or numerical digits, given on some special pattern which look likes some code. You have to look and analyze and answer according to it. In this first you have to look the both letter code and notice the numeric digit coded to that alphabet, and answer the common pattern available in the option.

Example:

If “ADDA” is coded as “5885”, “PEN” is coded as “147″, how is “EDEN” coded in the same language?

Solution:-

 

  • SYMBOL CODING:

Symbol Coding are based on Symbols. In this type of coding either alphabetical code are assigned to symbols or symbols are assigned to alphabets.

Example:

If “LESD” is written as “ @ $ & # “  , “NAC” is written as “ % ? * “, how “CANDLES” is coded in the same way?

Solution:-

 

  • NUMBER-LETTER MIXED CODING:

This type of coding are based on statements. Words in statement are coded by numbers. You have to look letters and notice the numeric digit coded to that letter, and answer the common pattern available in the option.

Example:

If “GOVERNMENT ADDA IS BEST” is coded as “ 8 6 4 2”, “GET BEST PREPARATION” is coded as “ 1 5 4 ”, “ GET GOVERNMENT JOB” is coded as “ 6 5 9 ”, how “BEST GOVERNMENT” is coded in the same way?

Solution:-

From the above statements we have to find the common words in the statements, and accordingly find the numeric code for the same word.

GOVERNMENT ADDA IS BEST = 8 6 4 2

GET BEST PREPARATION = 1 5 4

From, the above statement BEST is common in the statement and 4 is common in the code. So the code for BEST=4

GOVERNMENT ADDA IS BEST = 8 6 4 2

GET GOVERNMENT JOB = 6 5 9

From, the above statement GOVERNMENT is common in the statement and 6 is common in the code. So the code for GOVERNMENT=6

ANSWER:- BEST GOVERNMENT= 4 6

Solutions

  1. (1) In the code each of the two letters are reversed in arrangement.2. (4) In the code the arrangement of the letters in the word is wholly reversed.3. (2) The letters preceding the first, third and fifth letters of the given word and those succeeding the second, fourth and last letters of the word in the alphabet form the code.4. (5) The 1st and the last letters of the word are kept as such in the code and all other letters in between them are wholly reversed.5. (1) In the code, the first letter is the second alphabet, the second letter is the third alphabet, the third letter is the fourth alphabet and so on after the corresponding letter in the word.6. (1) The letters are coded accordingly T as 8, W as 6, E as 3, L as 2, and V as 0. So TWELVE is coded as 863203.7. (2) The letters are coded accordingly P as 2, E as 4, A as 1, R as 5 and L as 3. So PEARL is coded as 24153.8. (2) The letters are coded accordingly S as 2, E as 1, A as 4, R as 6, C as 7 and H as 3. i.e., 2146739. (5) In the first and the second statements the common words are ‘are’ and ‘you’ and the common code words are nee and see. So nee and see means are and you. In the second statement the remaining code ble means where.10. (3) In the first and the second statements, the common code word is nae and the common word is green. So nae means green. In the first and the third statements, the common code word is tom and the common word is is so tom means is. Therefore in the first statement pit means apple.11. (1) In the first and the second statements the common code is tingo and the common word is flower. So tingo means flower. In the second and the third statements, the common code is mst and the common word is sweet. So mst means sweet. Therefore in the second statement, rho means fragranee.12. (3) In the first and the third statements, the common code digits are 4 and 3 ; and the common words are mangoes and are. So 4 and 3 are the codes for mangoes and are. Thus in the third statement 9 means ripe.13. (3) In the first and the second statements, the common code digit is 2 and the common word is carpet. So 2 means carpet. In the second and the third statements, the common code digit is 6 and the common word is one. So 6 means one. Therefore in the second statement, 5 means dust.

    14. (4) In the first and the second statements, the common code digit is 4 and the common word is good. So 4 stands for good. In the second and the third statements, the common code digit is 7 and the common word is pictures. So 7 stands for pictures. Thus in the second statement 8 stands for see.

    15. (1) In the first and the second statements, the common code digit is 5 and the common word is old, so 5 stands for old. In the first and third statements, the common code digit is 3 and the common word is books so 3 stands for books. Thus in the first statement, 2 stands for are.

    16. (3) The first letter is moved one step backward and second is moved one step forward the third letter is moved one step backward, the fourth letter one step forward and so on. So the answer is (3)

    17. (2) Each letter of the word is three steps ahead of the corresponding letter of the code.

    18. (4) The groups of second and third letters and fourth and fifth letters in the word interchange places in the code.

    19. (1) As given 1 is coded as X, 6 is coded as T, 3 is coded as J, 5 is coded as C, 4 is coded as N and 2 is coded as Z. So 163542 is coded as XTJCNZ.

    20. (2) As given 9 is coded as Q, 2 as Z, 5 as C, 8 as F, 7 as O and 3 as J. So 925873 is coded as QZCFOJ.

    21. (4) 7 is coded as O, 4 as N, 1 as X, 5 as C, 6 as T and 8 as F. So 741568 is coded as ONXCTF.

    22. (3) O  R  A  N  G   E   E  A  T

    ?   ÷   @  •   +   *   *  @  $
    So we can codeROTATE as  ÷ ? $ @ $ *

    23. (5)
    P – £
    A – @
    L – ?
    M – $
    R – *
    M – $
    ALARM @ ? @ $ £ *

    24. (1)
    H – ?
    A – $
    T – @
    F – 
    I – £
    N – •
    G – &
    E – *
    R – #
    FATHER  $ @ ? * #

    25. (2)
    B – @
    O – $
    D – *
    E – ?
    A – •
    T – £
    DEBATE = * ? @ • £ ?
