# Coding Decoding Questions & Answers (Download PDF): Practice 50+ Solved Questions for SSC/RRB/UPSC/ Banking/Defence/ Teaching Govt Exams

Updated: May 17, 2022 11:34 IST 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.

## Types of Coding-Decoding Questions

The questions on coding and decoding are basically of three types as given below:

### 1. LETTER TO LETTER CODING

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.

### 2. LETTER TO NUMBER CODING

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.

### 3. CODING OF A WORD IN A SENTENCE

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.
