Reasoning and Quantitative AptitudeCoding-Decoding Module Name: Coding and Decoding SITAMS Page 1 Reasoning and Quantitative Aptitude MOUDULE OBJECTIVE: Coding-Decoding This module is used to improve mental ability of a person. A CODE is a ‘system of signals’. Therefore, Coding is a method of transmitting a message between the sender and the receiver without a third person knowing it. Before transmitting, the data is encoded and at receiver side encode data is decoded in order to obtain original data by determining common key in encoded data. The Coding and Decoding Test is set up to judge the candidate’s ability. The Coding and Decoding is classified into seven types according to the on what way it is doing. They areype Type1: Letter Coding. Type2: Number Coding. Type3: Matrix Coding. Type4: Substitution. Type5:Mixed Letter Coding. Type6:Mixed Number Coding. Type7:Deciphering Individual Letter Codes by Analysis. SITAMS Page 2 in FREEZE. Clearly each letter in the word TAP is moved one step backward to obtain the corresponding letter of the code. R as Q.E as D and Z as Y. in NEMESIS. If TAP is coded as SZO. S Z O -1↑ T A P Thus. Clearly. M Y S T I F Y +1↓ N Z T U J G Z So. if in a certain language MYSTIFY is coded as NZTUJGZ. Case1:To form the code for another word 1. the code becomes EQDDYD SITAMS Page 3 . each letter in the word MYSTIFY is moved one step forward to obtain the corresponding letter of the code. the code becomes OFNFTJT.B. N will be coded as O. M as N and so on. 2.R.Reasoning and Quantitative Aptitude Coding-Decoding SOLVED EXAMPLES: Type1:Letter Coding: In this type the real alphabets in a word are replaced by certain other alphabets according to a specific rule to form its code. E as F. F will be coded as E. So. Thus.B.A. 1997) Sol. 1997) Sol.S. then how is FREEZE coded? (M. the candidate is required to detect the common rule and answer the questions accordingly. how is NEMESIS coded in that language? (B. which word will be coded as HOUSE? SOL: each letter of the word is one step ahead of the corresponding letter of the code B Z Q Q N L | | | | | | C A R R O M H | | I U S E | | | P V T F O So.S.1996) SOL: Clearly. Reversed in order. I f in a certain language CARROM is coded as BZQQNL. S as T and E as F. The candidate is required to analyse the code as per the directions. MENTION is written as LNEITNO. in PATTERN. U as V. In a certain code. either numerical code values are assigned to a word or alphabetical code letters are assigned to the numbers. O as P. taking two at a time . BIDDIC is coded as 294493 6. Case 1: when a numerical code values are assigned to words 5. to obtain the code. TYPE 2: NUMBER CODING In these questions. the first letter of the word MENTION is moved one step backward and the remaining letters are. Thus.Reasoning and Quantitative Aptitude 3. if in a certain language A is coded as 1. P will be coded as O. HOUSE is coded as IPVTF. How is PATTERN written in that code? (B.Tax. The answer is OTAETNR.D as 4 and C as 3. and the sequence of the remaining letter in the cod would be TAETNR.B is coded as 2. in the given code. Case 2: To find the word by analyzing the given code (DECODING) 4. how is BIDDIC is coded in that code? (Assistant Grade.R. Thus the code becomes OTAETNR. B is coded as 2.B. H is coded as I. 1998) Coding-Decoding SOL: Clearly. I as 9. then how would you encode ACCEPT? (I. the alphabets are coded as follows SITAMS P A I N T E X C L Page 4 . If PAINT is coded as 74128 and EXCEL is coded as 93596.1995) SOL:As given the letters are coded as A B C D E F G H I 1 2 3 4 5 6 7 8 9 So in BIDDIC.and so on .So. Hence. 9 as Q. 3 as N. So.Tax & Central Excise.66.78. find COLD?

C can be coded as 04. the correct code is 455978. 5 as R.85 or 96.O can be coded as 57. 1996) (b)31. How is 599423 coded in that code? SOL: Clearly as given 5 is coded as R.69. a word is represented by only one set of numbers as given in any one of the alternatives .31 or 44. 7. Coding-Decoding Case2: Number to letter coding. 4 as A. Examples: MATRIX 1 0 1 2 3 4 0 D C K K E 1 K D C C D 2 A K E D A 3 E A A E K 4 C E D A C MATRIX 2 5 6 7 8 9 5 P T P O L 6 L P N N O 7 O N T T P 8 T L O P N 9 N O L L T (I. 4 as A and 6 as B. Hence. A is coded as 4.99.24 8.85. 2 as P.86.22 (c)30.79.95. E as 9. From matrix 2. 9 as Q. In a certain code. 2 is coded as P.21. TYPE 3: MATRIX CODING In this type of questions.22 SOL: SITAMS From matrix 1. P as 7 and T as 8.77.Reasoning and Quantitative Aptitude 7 4 1 2 8 9 3 5 6 So. But. Through a comparison of the given coded messages. taking two at a time. 1995) (a)chn (b)nhi (c)ptr (d)wop SOL: (d). D can be coded as 00. as given. are given. only (d) contains all correct codes. In the second and third statements the common word is ‘gives’ and the common code word is ‘wop’.32 or 41.24. TYPE 4: SUBSTITUTION In this type of questions. 9. which is the cheapest jewel ? SOL: We know that ‘SILVER’ is cheapest. who will teach in a class? SOL : Clearly. 11. RUBY is the cheapest. GOLD is called SILVER. SILVER is called RUBY and RUBY is called EMERALD. The common code word will mean that word. If DIAMOND is called GOLD .L can be coded as 56.89 or 95. BUTLER is called MANAGER. what would mean ‘gives’? (Assistant Grade. So a CLERK will teach in a class. ‘tti wop nhi’ stands for ‘he gives nothing’. 10. ‘SILVER’ is called ‘RUBY’. So. TEACHER is called CLERK. To analyses such codes. three or four complete messages are given in the coded language and the code for a particular word is asked. ‘ptr lnm wop chn’ stands for ‘wife gives marriage gift’.79. any two messages bearing a common word are picked up. So ‘wop’ means ‘gives’. TYPE 6: MIXED NUMBER CODING In this type of questions. CLERK is called PRINCIPAL. Then a question is asked that is to be answered in the code language. the entire message can be analyzed. a TEACHER teaches in a class and as given TEACHER is called CLERK. TYPE 5: MIXED LETTER CODING In this type of questions.11. SITAMS Page 6 .Reasoning and Quantitative Aptitude From matrix 2. MANAGER is called TEACHER.68. a few groups of numbers each coding a certain short message. some particular objects are assigned code names. Coding-Decoding Clearly. Proceeding similarly by picking up all possible combinations of two. If COOK is called BUTLER. If ‘nso ptr kli chn’ stands for ‘sharma gets marriage gift’. From matrix 1. in the first statement ‘7’ means ‘very’. ‘958’ means ‘hard work pays’ and ‘645’ means ‘study and work’. ’6’ means ‘study’. certain simple words are given along with their codes.Reasoning and Quantitative Aptitude the candidate is required to find the number code for each word and then formulate the code for the message given. the common word is ‘study’ and the common code digit is ‘6’. Coding-Decoding TYPE 7: DECIPHERING INDIVIDUAL LETTER CODES BY ANALYSIS In this type of questions.I. SOLACE (a)aedpqr SITAMS (Hotel Management..O. the common word is ‘hard’ and the common code digit is ’8’.B. and then answer the given questions accordingly. In the first and third statements. ‘8’ means ‘hard’. In a certain code.1996) (b)acemoq (c)acdmpq (d)demopq Page 7 . Which of the following is the code for ‘very’? (S. Thus. So. taking two words at a time. 1994) SOL: In the first and second statements. EX : COLUMN 1 DELIBERATION CONSIDERATE GHOSTLIKE cfhmoqqrx WORLDLY cdgmqrsxz KNOWLEDGE adefmopqqsz ROCKET cefkmopqqszz COLUMN 2 aemrqs ccehlmo 13. The candidate is required to decipher individual codes for different letters by comparing. 12. So.P. ‘786’ means ‘study very hard’. The information can be summarized as bellow: code m e c o h l Q r s a x f z d g p k letter O R L D W Y E K T C G N I S H A B FOR SOLACE: The code for ‘S’ is ‘d’.Reasoning and Quantitative Aptitude SOL: we first find the exact codes for given word.So its code is adefmopqqsz. Similarly find code letters for others. for ‘A’ is ‘p’.for ‘O’ is ‘m’. CONSIDERATE is a 11 letter word. In WORLDLY and ROCKET. SITAMS Page 8 . Coding-Decoding DELIBERATION is a 12 letter word. Hence its code is cefkmopqqszz. So. the code for SOLACE is ‘dmcpaq’ or ‘acdmpq’. code letter for O is ‘m’. In all words the common letter is ‘O’ and common code letter is ‘m’. the common letters are O & R. for ‘L’ is ‘c’. then other common code letter ‘e’ stands for R. Similarly find for another words.Hence ‘O’ means ‘m’. for ‘C’ is ‘a’ and for ‘E’ is ‘q’. how is NEGATIVE coded in that code ? (B.in the same code. each letter in the word is moved one step forward to obtain the corresponding letter of the code.
