Letter Coding Decoding - Tabular
Introduction
For conveying secret messages from one place tp another , especially in Defence Services, coding is used. The codes are based on various principles/patterns such that the message can be easily be deciphered at the other end. Now-a-days, in certain competitive examinations, such questions are given to judge the candidates intelligence and mental ability. They are required to encode and decode words and sentences after observing the pattern and principles involved. It is always easy to handle numbers than alphabet letters. So, if there is a set of questions on alphabet coding in the exam, it is better to use this table to decipher the code.
Decoding the Rule Applied
This part of coding test required a careful examination of rules followed to code a certain word. Only after the analysis of the pattern applied in coding, you can decode them.
Example
Study the five different ways of coding marked (1), (2), (3), (4) & (5). A specific rule has been applied to codify each of them. Can you find out the rule of coding applied in the question that follows.
| FRANCE | (1) N C E F R A |
| (2) F A C R N E | |
| (3) E C N A R F | |
| (4) A C E F N R | |
| (5) F E R C A N |
| S. No. | WORD | CODE |
| 1 | C A N A D A | C N D A A A |
| 2 | K E N Y A | K A E Y N |
| 3 | N A T I O N S | S N O I T A N |
| 4 | V A N D A N A | V N A A A D N |
| 5 | V A R D H M A N | N A M H D R A V |
| 6 | V A R I O U S | A I O R S U V |
| 7 | C A R E E R | E E R C A R |
| 8 | P O P U L A T I O N | P N O O P I U T L A |
| 9 | M E D I C I N E | M D C N E I I E |
| 10 | A P T I T U D E | A D E I P T T U |
Answers:
1. ( 2) 2. (5) 3. (3) 4. (2) 5. (3) 6.(4) 7.(1) 8. (5) 9. (2) 10.(4)
Explanations:
The rules by which the different pattern of coding is made are as follows.
(1) The former part (FRA) gets transferred after the latter part (NCE). The coding is made in the order given below:
(2) The pattern is that every letters gets transferred on the adjacent line of the code.
(3) The sequence is the backward rearrangement of letter.
(4) The sequence is the rearrangement of letters with respect to the order of regular of alphabets. So FRANCE is coded as A C E F N R. This coding as according to the alphabetical order starting with A = 1
(5) The first and the last letters are made the first two letters in the code the second and the fifth letter are made the third and fourth letters in the code the third and the fourth letters are made the last two letters respectively.
