Coding Decoding Questions & Answers (Download PDF): In Government exams like, SSC, Railways, UPSC, Defence, Banking, Teaching & other State Govt Exams, you will find a question asked every year from Coding-Decoding topic of Reasoning Section. Coding-Decoding is an integral part of the Logical Reasoning section in many competitive exams. It basically judges the candidate’s ability to decipher the code language. In each question of this topic, a word and a coded form of the word will be given. Students are required to decode the logic behind this coding and then apply the same logic to another given word for finding the answer in the form of a code.
The questions on coding and decoding are basically of three types as given below:
Example: In a certain code ‘SHIMLA’ is written as ‘RGHLKZ, how will PATNA be coded then?
Solution: 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 be coded as OZSMZ.
Example: DAZE is written as 41265 in a certain code. How will BOY be written in the same code?
Solution: In this question the position of each alphabet is given like
D = 4, A = 1, Z = 26 and E = 5.
So, the code for BOY will be 21525 as B = 2, O = 15 and Y = 25.
Example: 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’?
Solution: 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.
Directions (Q. 17 – 20): In each of the following questions, a word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two given matrices. The columns and rows of Matrix I are numbered from 0 to 4 and those of Matrix II from 5 to 9. A letter from these matrices can be represented first by its row and then the column number e.g., in the matrices for questions 1 to 4, M can be represented by 14, 21, etc.; O can be represented by 20, 32, etc. Similarly you have to identify the correct set for the word given in each question.
Matrix I
0 1 2 3 4 0 F O M S R 1 S R F O M 2 O M S R F 3 R F O M S 4 M S R F OMatrix II
5 6 7 8 9 5 A T D I P 6 I P A T D 7 T D I P A 8 P A T D I 9 D I P A T22. If P means 'add to', V means 'multiply by', M means 'subtract from' and L means 'divide by' then
