Number Coding Decoding
NUMBER CODING DECODING: For conveying messages from one place to another, especially in Defence Services, coding is used. The codes are based on various principles/patterns such that the message can be easily to 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.
Coding with Numerical Digits:
The pattern of coding with numeric digits is similar to that of coding with alphabets except the use of numerical digits with the assignment of some artificial values. The values are allotted based on some specific pattern which has to be discerned by the candidate in order to solve the problem in the quickest possible time.
If TRAIN is coded as 23456, how will you code TIN and RAIN?
The answer will be 256 for TIN and 3456 for RAIN . T = 2, R = 3, A = 4, I = 5, N = 6. These values have been allotted arbitrary based on logical relationship, the candidates will be able to solve the problem.
In a certain code, the letter of English alphabet (consonats and vowels) are coded as given for same words. the numeric code for each letter is given in bracket under coded form and correspods to the letter in the word in the same serial order. Study the coded forms of the given words and find out the rules for their codification. Appliying those rules, answer the questions that follow in two sets. Word Coded Form SEAT [5] [15] [15] [5] CUT [5] [10] [5] ONE [0] [5] [0] DEEP [5] [20] [20] [5] POUR [5] [15] [15] [5] PIN [5] [10] [5] NONE [5] [25] [5] [25] BOOK [5] [20] [20] [5] OPEN [30] [5] [30] [5] ATE [0] [5] [0] PAGE [5] [25] [5] [25] UNIT [30] [5] [30] [5] AGED | |||
