1. Coding based on Alphabet
2. Coding based on Numerals
3. Coding based on Symbols and numerals
4. Coding based on a group of words
5. Coding based on reasoning
Coding based on Alphabet
Reversal coding
Example 1. If in a certain language, MADRAS is coded as SADDAM how is BOMBAY coded in that code?
A. BAYMOB
B. BMYOBA
C. YABMOB
D. BOYAMB
Explanation: Tthe order of letters has been revered in code. Following the coding given above BOMBAY will be coded as YABMOB. Hence the answer is (D).

Example 2. If in a certain language, DINESH is coded as WRMVHS how is KUMAR coded in that code?
A. LVNBS
B. MARUK
C. PFNZI
D. URAMK
Explanation: We know that W is the opposite letter of D, R is opposite letter of I. It shows that the coded word contains all the opposite letters. Keeping this view we know that KUMAR will be coded as PENZI. Hence the answer is (C).
Coding using proceeding and following letters
Example 3. If in a certain language, PENCIL is coded as QDOBJK how is TRIPPLE coded in that code?
A. CHRONRD’
B. DSOESPI
C. UQJOQKF
D. QUOQJKF
Explanation: We observe that letters are alternatively move one place forward and one place backward. Based on this observation we coded the word TRIPPLE as UQJOQKF. Hence the answer is (C).
Example 4. If in a code language, MOSCOW is written as WSOOCM how will MARGIN is written in that code?

Hence the answer is (A).
Reducing two alphabets to one word
Example 5. If in a certain language, FIGURE is coded as ILI how is DECODE coded in that code
A. ITI
B. TII
C. IIT
D. ITO
E. None of these
Explanation:

9=I |
20=T |
9=I |

Hence the answer is ITI denoted by (A)
Given two words and to find code for third
Example 6. If the word NUMBER is coded as ‘EPRSAY’ and ‘SQUARE’ is coded as ‘NGPVYA’ then how done code MEMBER?
A. RARSYA
B. RRASYA
C. RARSAY
D. SARSAY
E. None of these
Explanation:

If we observe from above table, M is coded as R, E is coded as S, So the answer is (A)
Coding based on numerals and symbols
Example 7. 35796 is coded as SURAJ, 48217 is coded as KUMAR then how 7143686 will be coded?
A. RASKJJU
B. RAKSJUJ
C. JUJRAKS
D. KARSJUJ
Explanation:

7 is coded as R, 1 is coded as A by following this process we design a code RAKSJUJ for 7143686. Hence the answer is (B).
Example 8. if FIGURE is coded 10-13-11-25-22-9 how will you make code RECEIVE ?
A. 22-9-7-9-13-26-9
B. 22-7-9-13-9-26-9
C. 9-13-9-26-9-22-7
D. 13-26-22-9-7-9-9
The explanation we observed that every letter is assigned code obtained by adding 4 to the numeral denoting the position of that letter in the English alphabet. Hence the answer is (A).
Example 9. if D=5, DON=33, find ROSE
A. 58
B. 57
C. 60
D. 61
E. None of these
Explanation: Clearly putting the value of letter position in the English alphabet
A=1, B=2, C=3, ………..Y=25, Z=26
ROSE = 18+15+19+05
ROSE = 57. Hence the answer is (B)
Example 10. If FEATURE is code as G21U5S2 then finds code of INFORMATION
A. 3OG4SNIU34O
B. 3G4O4SNIU34
C. G4043SNIU43
D. SNIU34430G4
E. None of these
Explanation: We observe that each letter incremented by one letter and put the number value in place of vowels in the given code, so the answer is (A)

Example11. In a certain code, TOME is coded as?$@# and MORE is code as @$&# how will you find code of REMOTE
A. @&?##&
B. &#@$?#
C. &#@$?#
D. @$?*&%
Explanation:

O |
M |
E |
M |
O |
R |
E |
|
? |
$ |
@ |
# |
@ |
$ |
& |
# |
Did we observe that? is code of T, @ is code of M by following this process we make code &#@$?#. Hence the answer is (B)
Example 12. If in a certain code of language 851 means good sweet fruit and 783 means good red rose and 341 means rose and fruit which of the following digit stands for sweet?
A. 8
B. 5
C. 1
D. 3
E. None of these
Explanation: In first and second statements common digit is 8 and the common word is good so 8 stands for good. In first and third statements common digit is 1 and the common word is fruit, so 1 stand for fruit, so therefore in first statement 5 stand for sweet. Hence the answer is (B).
