In this post we will discuss questions on coding and decoding which is important part of non verbal ability syllabus. The questions of coding and decoding is frequently asked in competition exams like GRE, GMAT, Math Olympiad, CAT, MAT, CMAT, NMAT, SNAP, SSC, IBPS, Banking, RRB exams.

One easy way to solve these questions is by drawing flowchart/illustration relationships between the parameters. In all the questions given below, we have tried to provide you solutions step by step so that you can understand the concept fully.

## Coding & Decoding solved questions

**Q1. ** If REQUEST is written as S2R52TU, then how will ACID be written ?

(a)1394 (b) IC94

(c) BDJE (d) None of these

**Solution**-Arranging the each word corresponding to their code

Here vowels are coded in digits that is A, E, I, O, U AS 1, 2, 3, 4, 5

And all consonant is moved 1 step forward in alphabetical order

So ACID is represented as

Hence **1D3E** is our answer

**Q2. **In a certain code, the word DEAL is coded as 4 – 5 – 1 – 12. Following the same rule of coding, what should be the code for the word LADY ?

(a)12 – 4 – 1 – 25 (b) 12 – 1 – 4 – 25

(c)10 – 1 – 4 – 23 (d) 12 – 1 – 4 – 22

**Solution**-Here each letter is coded by the numeral denoting its position in the english alphabet that is

Hence **12 – 1 - 4 – 25** is our answer

**Q3. **If GO = 32, SHE = 49, then SOME will be equal to

(a)56 (b) 58

(c) 62 (d) 64

**Solution**-In this question letters are coded by the letters from backward direction in same position of alphabetical order

And adding their numeral values we get its code that is

So SOME represent as

Hence **56** is our answer

**Q4. **If ZIP = 198 and ZAP = 246, then how will you code VIP ?

(a)174 (b) 222

(c) 888 (d) 990

**Solution**-Here by taking reverse of the given letter and then by adding 1 in their number place so that we get here

Z I P = (Z + I + P) = (2 + 19 + 12) =**33**

After multiplying it with 6 we get

Z I P = (Z + I + P) × 6 = **33 ****× ****6** = **198**

So for VIP we get code as

V I P = (V + I + P) × 6 = (**6 + 19 + 12**) × **6** = **222** Hence **222** is our answer

**Q5**. If HOSPITAL is written as 32574618 in a certain code, how would POSTAL be written in that code ?

(a)752618 (b) 725618

(c) 725168 (d) 725681

**Solution** –Here we arrange all the letters according to their given code

Here all letters have their unique code

So POSTAL can be written as

Hence **725618** is our answer

**Q6**. If HONESTY is written as 5132468 and POVERTY as 7192068, how is HORSE written in a certain code ?

(a)50124 (b) 51042

(c) 51024 (d) 52014

**Solution** –Here we arrange all the letters according to their given code

Here all letters have their unique code

So HORSE can be written as

Hence **51042 ** is our answer

**Q7**. If J = 10, JASMINE = 71, then ESTIMATE = ?

(a)71 (b) 82

(c) 92 (d) 91

**Solution**– Here each letter is coded by the numeral denoting its position in the english alphabet that is

In same way ESTIMATE is written as

Hence **92** is our answer

**Q8. **If A = 1, CAT = 24, then POLICE = ?

(a)57 (b) 60

(c) 62 (d) 59

**Solution**– Here each letter is coded by the numeral denoting its position in the English alphabet that is

In same way POLICE is written as

Hence **60** is our answer

**Q9**. If BEAUTIFUL is written as CDOGHJKMN, how LEAF can be written in that code ?

(a)NDOK (b) KNND

(c) ODNK (d) DKON

**Solution**– Here each letter are coded to their next letter of English alphabet that is

In same way LEAF is coded as

Hence **NDOK** is our answer

**Q10**. If LOSE is coded as 1357 and GAIN is coded as 2468, what do the figures 84615 stand for ?

(a) NAILS (b) SNAIL

(c) LANES (d) SLAIN

**Solution **–Here we arrange all the letters according to their given code

Here all letters have their unique code

So 84615 can be written as

Hence **NAILS** is our answer
