The coding and decoding test is designed to test the candidate's ability.The term Coding and Decoding relates message. Coding is method of transmitting a message between sender and receiver that no third person can't understand it. Coding, therefore, means rule or method used to hide the actual meaning of a ward or group of wards and Decoding means the methods making out the actual message that is disguised in coding.
Based on various type of questions asked in different examinations, it is divided into 4 types of categories.
1. Letter Coding
2. Number Coding
3. Substitution Coding
4. Mixed Coding and Mixed Number Coding
To solve the questions of this section,the candidate has an idea about the Alphabet letter series. In the below has been given a forword letter series, reverse letter series and opposite letter series.
Alphabet Numbering:
1 2 3 4 5 6 7 8 9 10 11 12 13
A B C D E F G H I J K L M
N O P Q R S T U V W X Y Z
14 15 16 17 18 19 20 21 22 23 24 25 26
Alphabet second half Reverse Order:
A B C D E F G H I J K L M
Z Y X W V U T S R Q P O N
Alphabet forward order:
A B C D E F G H I J K L M
N O P Q R S T U V W X Y Z
Some examples to under stand coding and decoding:
1.Interchanging of positions
Example:In a certain code IMTITJU is written as TMIIUJT.How is TEMREMP written in that code?
Explanation:The given code contain 7 letters.In the given code, the letters of even numbered position have been left as they are while the first and third letters have been interchanged.similarly,the fifth and seventh letters have been interchanged.similarly,for TEMREMP solution is METRPME.
2. Addition/Substraction of Alphabet numeric position value
Example:In certain code of MTUXTRVN is written as NUVXTQUM.how is ASUMNJKL written in that code ?
Explanation: There are 8 letters in the word.the codes for first three letters can be obtained by ( taking followin letters )adding +1 to the position of alphabet numeric value.the fourth and fifth letters are written as they are in the word and the last three letters have by taking preceding letters.so,the solution become's NUVXTQUM.
3. Number coding
Example:if PRIVATE is coded as 1234567 and RISK is coded as 2398,how RIVETS coded ?
Explanation: By comparing PRIVATE and RISK codes R=2,I=3....they code numbers in serial to PRIVATE. So,solution we get 234769.
4. Substitution Coding
Example: In a code language ' We Me Ye' means "Tell Them Young" and 'Me Yo Na Ye' means 'Wise Young Sharp Tell'.which code represents 'Them' in the given code language ?
Explanation: By Comparing two codes Me and Ye are seems in two codes.where,Them is not there in second code.so,Them in code language is 'We'.
In some rare number coding problems coding requires squares or cones of alphabate position numeric value.example for this case is: if a certain code Z=2197 and R=729 how would J be written in that code.
For this we may go in different trials or ways.but,the correct procedure is The position value Z is 26 and half of 26 is 13,qube of 13 I'd 2197.similarly, J position value 10.half of 10 and qube is 125.so,solution is 125.
Upto now I have gone through so many coding and decoding problems.but,I felt some difficulty to get answer to the following question.
Problem:In certain code language COMPUTER is written as RFUVQNPC. How will MEDICINE be written in that code language ?
Note:First try it on your own and then see the explanation
Explanation:There are 8 letters in the word.the coded word can be obtained by taking the immediately following letters of the word,but in reverse order.that means,in coded form the first and the last letters have been interchanged while the remaining letters coded by taking their immediate next letters in the reverse order.
So solution we get RFUVQNPC.
