R, E, T, P, A, H, C, , 2, Odd Man Out,, Coding and Decoding, Finding the odd man out from the given alternatives is a, very common type of questions that one comes across in, different competitive examinations. In the questions on, odd man out, all the items-except one-follow a certain pattern (in their formation) or belong to a group. The item, that does not follow the pattern or does not belong to the, group has to be marked as the answer choice., The problems of this variety often fall under the category of CLASSIFICATION. When a given set of elements, is classified under a single head, one of the items will not, fall into that group to which the rest belong, i.e., it will not, have the common property, which the others will have., Hence it becomes the odd man out., , Questions on classification can be asked in any form., Some of the commonly asked ones are given below., , (1) ALPHAbeT CLASSiFiCATiON, In this type, a group of jumbled letters typically consisting, of three letters, (but can be four or two or just a single letter) are put together. The pattern or order in which they, are grouped is to be studied and we need to find out which, groups have the same pattern or relationship between the, letters. There will be one choice, which will have a pattern, different from the rest and that is our answer., , Solved examples, 1. Find the odd one among the following., (1) ZW, (2) TQ, (3) SP, (4) NL, , , , Solution: Z -3W, T-3Q, S -3P, N-2L, P–3M, Hence, NL is the odd one., Choice (4), , 2. Find the odd one among the following., (1) CFD, (3) KNM, , , , (2) GJH, (4) JMK, , Solution: C+3F-2D, G+3J-2H, K+3N-1M, J+3M-2K,, , V+3Y–2W, , Hence, KNM is the odd one., Choice (3)

(2) WOrD CLASSiFiCATiON, Here, different items are classified based on common properties like names, places, professions, parts of speech, etc. A few, examples are illustrated below., , Solved examples, 3. Find the odd one among the following., (1) Mercury, (2) Moon, (3) Jupiter, (4) Saturn, , , , Solution: All others except Moon are planets, where as Moon is a satellite., Choice (2), , (3) NuMber CLASSiFiCATiON, In this case, we need to choose the odd number from the, given alternatives. The numbers may belong to a particular, set, i.e., they may be odd, even, prime, rational, squares,, , 4. Find the odd one among the following., (1) SORE, (2) SOTLU, (3) NORGAE, (4) MEJNIAS, , , , Solution: The words are jumbled. The actual, , words are ROSE, LOTUS, ORANGE, JASMINE, and LILLY. All, except ORANGE, are flowers, whereas ORANGE is a fruit., Choice (3), , cubes, and they may also be coded into binary digits (involving 0’s and 1’s) etc. and only one of the choices will not, follow the rule which others do and that is our answer. A, few illustrations are given below., , Solved examples, 5. Find the odd one among the following., (a) (1) 17, (2) 27, (3) 37, (4) 47, , , , (b) (1) 441, (3) 361, , (2) 289, (4) 343, , (c) (1) 1011, (3) 1111, , (2) 1101, (4) 10001, , Solution:, (a) All the given numbers except 27 are prime, numbers whereas 27 is a composite number., Choice (2), (b) The given numbers can be written as(21)2,, (17)2, (19)2, (7)3, (25)2All except 343 are the, squares whereas 343 is a cube., Choice (4), , (c) The given numbers are in binary system, converting these into the decimal system we get,, 1011, ⇒ 1 × 23 + 0 × 22 + 1 × 21 + 1 × 20, = 8 + 2 + 1 = 11, 1101 ⇒ 1 × 23 + 1 × 22 + 0 × 21 + 1 × 20, = 8 + 4 + 1 = 13, 1111 ⇒ 1 × 23 + 1 × 22 + 1 × 21 + 1 × 20, = 8 + 4 + 2 + 1 = 15, 0001 ⇒ 1 × 24 + 0 × 23 + 0 × 22 + 0 × 21 + 1 × 20, = 16 + 1 = 17, 111 = 1 × 22 + 1 × 21 + 1 × 26, =4+2+1=7, All the given numbers except 15 are prime, numbers., Choice (3)

Before looking at the different types of questions and, some of the codes that can be used with the help of examples, let us first understand what we mean by coding and, decoding. When we say coding, a particular code or pattern, is used to express a word in English language as a different, word or in a different form. The coded word itself does not, make any sense unless we know the pattern or code that has, , been followed. Decoding refers to the process of arriving at, the equivalent English word from the code word given., In the questions, a particular code is given and on the, basis of this given code, we have to find out how another word (in English language) can be coded. The correct, code for the given word has to be selected from the answer, choices on the basis of the code given in the question., , Solved examples, 1. In a certain code language, if the word ‘PARTNER’, is coded as OZQSMDQ, then what is the code for, the word ‘SEGMENT’ in that language?, (1) TFHNFOU, (2) RDFLDMS, (3) RDELDMS, (4) RDFEDNS, , , , Solution:, Word :, P A R T N E R, Logic :, -1 -1 -1 -1 -1 -1 -1, Code :, O Z Q S M D Q, Similarly the code for SEGMENT is, Word :, S E G M E N T, Logic :, -1 -1 -1 -1 -1 -1 -1, Code :, R D F L D M S, Choice (2), , 2.

(3), (4), (5), (6), , STAIR, FORMAL, COMMON, FOR, , -, , efgnv, bensyz, zabzpb, ebs, , In the first word, the letter N is repeated and so is, the code a. Hence, for N, the code is a. Similarly,, from the second word, the code for E is ‘r’. In first, and sixth words the letter o is common and so is, the code b. Hence, the code for o is b. In the fifth, word, the letter m is repeated and so is the code z., Hence, the code for m is z. Similarly, the codes for, the remaining letters can be determined., The letters and their respective codes are as, follows:, , Letter, , A C E F I L M N O R S T, , Code, letter, , n p R s v y z a b e f G, , 3.
