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
