Jumbled Columnar Coding Decoding
Jumbled Columnar Coding Decoding
Introduction : Coding is a system of signals. This is a method of transmitting information in the form of codes or signals without it being known by a third person.The person who transmits the code or signal, is called the sender and the person who receives it, is called the receiver. Transmitted codes or signals are decoded on the other side by the receiver—this is known as decoding.
Jumbled Columnar Coding Decoding : In this type, we deal with questions, in which two columns are given. In column I few words are given and in column II their codes are given using a particular rule . The codes have been placed in jumbled order. We have to identify the code for particular word or letter
Example 1 : Column A contains certain words numbered from (1) to (6). Column B goes with the codes for column A, but with different order. You have to match the words of column A with their respective coded word in column B. The pattern of coding used here is BLADES = CMBEFT.
Column (A) Column (B)
(1) BASE (1) CBE
(2) BALE (2) CBTF
(3) SALE (3) CFE
(4) SAD (4) CBMF
(5) BAD (5) TBE
(6) BED (6) TBMF
Solution: By using the code : BLADES = CMBEFT. We can identify that in each alphabet, we add 1 to get the desired code:
Contrasting and Making Comparisons
A set of words are given in column I and codes have been formed in column II. Here in such questions some alphabets/letter are mentioned in column I and the corresponding codes in column II has been jumbled up thus making the question more difficult to correspond. To find the formula to decode these type of question some logical rule/principle is found by comparing or making contracts in all the questions. An example has been given below:
Example 2 : In the following question the capital letters in column I are codified in small letters in column II. The small letters are not arranged in the same order on the capital letters. Study the column (I) and (II) together and determine the small letters for the corresponding underlined capital letter in column (I).
Column (I) Column (II)
1. w b z b m
2. m b z x k
3. x k y o x
4. m t z b k
5. b e x o k
Answer : 1. w 2. m 3. y 4. z 5. e
Explanation:
If we compare question (1) & (2) we find that there are 3 alphabets (T, I, G) common and there corresponding small letters will be (m, z, b) though not in the same order. This leaves us with (D and R) with small alphabets (w and k). Therefore, we have now,
Either w or k is D's code
Now, if we taken (2) and (3), we find that w is not present is column II of either (2) or (3) and D is not there in column II of either (2) & (3) the or conclude that D = w and therefore R = k.
Now, carrying on with this finding, we see in question (3) and (5) there are two common elements in column I, V, E & R. Since E comes twice in (3), therefore code for E = x which leads to V = o and F =y in question is (1), I comes twice, this leads to I = b. So we are left with T and G which are either z or m.
Now, we cannot conclude anything more from these clues, but can fit in above observation to see what relation capital letters have with small letters.
A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
w | x | y | b | k | o | ||||||||||||||||||||
t | u | v | w | x | y | z | a | b | c | d | e | f | g | h | i | j | k | l | m | n | o | p | q | r | s |
According to the code language, words in capital letters in Column I are written in small letters in Column II The letters in Column II are jumbled up. Decode the language and choose the correct code for the word given in each question - ENVOY

Usually we see institutes offering objective based learning which usually causes a lag behind in subjective examinations which is the pattern followed by schools. I think it is really a work of planning to make us students grab the advantages of modes of examination, Objective Subjective and Onli...
