# Coding and Decoding – Logical Reasoning Questions

In this post we will solve coding and decoding questions which is important part of logical reasoning syllabus. If you are preparing for any competition exams like GRE GMAT, Math Olympiad, CAT, CMAT, NMAT, SSC, SSC-CGL, SSC-CHSL, Banking , IBPS, SBI etc. this chapter can be important for you.

We have tried to solve question with the use of illustrations for your easy understanding. I hope after reading the post you will gain some understanding to solve the questions yourself.

## Coding & Decoding Verbal Reasoning

Q1. If in a certain language, MADRAS is coded as NBESBT, how is BOMBAY coded in that language ?
(a) CPNCBX      (b) CPNCBZ
(c) CPOCBZ      (d) CQOCBZ

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code and we try to find that relationship

Here the coding of each letter is its next alphabet and follows +1 series
Now we have to find code for BOMBAY

By following above relationship we get our code for BOMBAY is CPNCBZ

Q2. If FISH is written as EHRG in a certain code, how would JUNGLE be written in that code ?
(a) ITMFKD      (b) ITNFKD
(c) KVOHMF    (d) TIMFKD

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code and we try to find that relationship

Here the coding of each letter is its previous alphabet and follows -1 series
Now we have to find code for JUNGLE

By following above relationship we get our code for JUNGLE is ITMFKD

Q3. In a certain code language, OPERATION is written as NODQZSHNM. How is INVISIBLE written in that code ?
(a) JOWJTJCMF          (b) JOWJTHAKD
(c) HMUHTJCMF       (d) HMUHRHAKD

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code And we try to find that relationship

Here the coding of each letter is its previous alphabet and follows -1 series
Now we have to find code for INVISIBLE

By following above relationship we get our code for INVISIBLE is HMUHRHAKD

Q4. If SUMMER is coded as RUNNER, the code for WINTER will be
(a) SUITER              (b) VIOUER
(c) WALKER            (d) SUFFER

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code and we try to find that relationship

Here the coding of each letter is following a different type of series
Now we have to find code for WINTER

By following above relationship we get our code for WINTER is VIOUER

Q5.  If, in a code, MIND becomes KGLB and ARGUE becomes YPESC, then what will DIAGRAM be in that code ?
(a) BGYEPYK          (b) BGYPYEK
(c) GLPEYKGB      (d) LKBGYPK

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code and we try to find that relationship

and for ARGUE

Here the coding of each letter is following a decreasing series of -2 in alphabetical order

Now we have to find code for DIAGRAM

By following above relationship we get our code for DIAGRAM is BGYEPYK

Q6.  In a certain language, SIGHT is written as FVTUG. How is REVEAL written in the same language ?
(a) YNRIRE          (b) DQHQMX
(c) FSJSOZ           (d) ERIRNY

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code and we try to find that relationship

Here the coding of each letter is follows a series of +13 series

Now we have to find code for REVEAL

By following above relationship we get our code for REVEAL is CPNCBZ

Q7.  If in a certain language, POPULAR is coded as QPQVMBS, then the code ‘GBNPVT‘ is used for which word?
(a) FARMER       (b) FAMOUS
(c) FRAMES        (d) FARMES

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code And we try to find that relationship

Here the coding of each letter is its next alphabet and follows +1 series
Now we have to find code for GBNPVT

By following above relationship we get our code for GBNPVT is FAMOUS

Q8.  If ROBUST is coded as QNATRS in a certain language, which word would be coded as ZXCMP ?
(a) BZEOR           (b) AYDNQ
(c) AWDLQ         (d) YWBLO

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code and we try to find that relationship

Here the coding of each letter is its previous alphabet and follows -1 series

Now we have to find code for ZXCMP

By following above relationship we get our code for ZXCMP is AYDNQ

Q9.  If in a certain language, GRASP is coded as BMVNK, then how the word ‘CRANE‘ will be coded?
(a) FUDQH         (b) HWFSJ
(c) GVERI           (d) XMVIZ

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code and we try to find that relationship

Here the coding of each letter follows a series of -5 in alphabetical

Now we have to find code for CRANE

By following above relationship we get our code for CRANE is XMVIZ

Q10.  In a certain code, DECEMBER is written as ERMBCEDE. Which word will be written as ERMBVENO in that code ?
(a) AUGUST             (b) SEPTEMBER
(c) OCTOMBER       (d) NOVEMBER

Solution-In this type of coding there is a particular relationship between the each letters of given word to their code

And we try to find that relationship

Here the pairs of letters are written as just opposite in their code

Similarly we write code for ERMBVENO

By following above relationship we get our code ERMBVENO for is NOVEMBER
