Coding Decoding test is to judge a candidate’s ability to decipher the code language. Coding is the process of converting a word into another language by using letters and numbers while decoding is to convert the coded value back into the normal language. In each question of this topic a word and coded form of the word will be given to the student. A student will required to decode the logic behind this coding and then apply the logic to another given word to find the answer in form of a code.
English alphabets and their corresponding number values helps the candidate to increase the performance in this area. The position of the letter in the English Alphabet is considered to be the value of the alphabet in questions on letter series. Also, when we are counting from A to Z, we again start with A, i.e. we treat the letters as being cyclic in nature. While attempting the letter series one should know the value of each of the alphabet as
Alphabets in natural series are:
The Word EJOTY is very helpful in finding the position of the alphabet as
For example, if we want to find the position of the alphabet ‘S’, then as we know that ‘T’ is 20, so ‘S’ is 20 - 1 = 19. Also, we can find the position of an alphabet from the end by subtracting its value from 27. For example, the position of D from the end is 27 – 4 = 23.
The pattern below is very useful to find many types of question in Alphabet Series when we write the last 13 alphabets in front of the first 13 alphabets of the English:
The questions on coding and decoding are basically of three types as given below.
I. LETTER TO LETTER
1. In a certain code ‘SHIMLA’ is written as ‘RGHLKZ, how will PATNA be coded then?
a) OZTMZ b) OZSMZ c) QBUMB d) OZTZM
Sol: Each letter is coded as the letter previous to it, i.e. S = R, H = G, I = H, M = L, L = K, A = Z. PATNA will become OZSMZ. Hence the answer is (b).
II. LETTER TO NUMBER
2. If LODES is coded as 46321, how will you code the word DOES?
a) 1234 b) 4321 c) 3621 d) 3261
Sol: Here, you will observe that all the letters of DOES are included in the letters of LODES, for which you have the code D = 3, O = 6, E = 2, S = 1. Therefore DOES = 3621. So, the answer is (d).
III. MISCALLANEOUS TYPES
3. In a certain code ‘415’ means ‘milk is hot’; ‘18’ means ‘hot soup’; and ‘895’ means ‘soup is tasty’. What number will indicate the word ‘tasty’?
a) 9 b) 8 c) 5 d) 4
Sol: The code for ‘hot’ is 1.So, the code of ‘soup’ is 8. Now the code of ‘is’ is 5. Hence we can say that the code of ‘tasty’ is 9. So, the answer is (a)
Questions From Previous Year Papers
Directions (Q. 1-2): Study the following information and answer the given question. [RBI Officer Exam – 2011]
In a certain way, ‘PROJECT’ is related to ‘CEOPRT’, ‘PLANE’ is related to ‘ELNP’ and ‘WIN’ is related to ‘NW’.
1. Following the same pattern, ‘ORGANISED’ will be related to
5) Cannot be determined
In every word, the middle element is dropped and rest of the alphabets are arranged in alphabetical order.
2. Following the same pattern, ‘DISTANCE’ will be related to
5) Cannot be determined
Answer: (5) Following the same pattern, DISTANCE cannot be related as it contains even number of alphabets while others contain odd number of alphabets. Therefore, there is no middle letter in the given word DISTANCE.
