5.Coding & Decoding
5.1 Introduction
5.1 Introduction
In this test letters, words or numbers are given which do not show their own real value but some other values. For example,
‘Tiger is coded as Cat’, while tiger can never be compared to Cat in real value. Thus, it implies that they show imaginary values.
Thus the given example that ‘Tiger is a Cat’ is an imaginary value. These imaginary values are said to be coded values and the
process is called coding. This coding is generally based on some particular rule. Candidates are required to find out that rule and
convert the coding into correct language or to convert the coding into corect language or to convert the correct language into coding.
This is called ‘Decoding’.
How can these questions be solved in less time ? For this each candidate should take care of following points-
The coding of each letter of the word in the question is done by writing the corresponding letter for that particular letter from reverse order.
OR
How has the coded word has been written, by subtracting or adding some particular number of letters for a letter in that word.
This is possible when the imaginary value and the given value for a word is matched.
The above facts can be made clear by the following examples-
Example 1.
If PERILOUS is written as RGTKNQWU in code language then how will OLYMPIC be written in that language ?
(A) QNOAKRE (B) QONARKE
(C) QNAORKE (D) QKNOARE
(E) QEKOARN
Answer with explanation (C)
Thus, here it is clear that in each letter of the word PERILOUS, 2-2 letters are added and the code word is obtained. Therefore,
we will apply the same rule in the word OLYMPIC to write the code word.
Example 2.
If ‘MENTAL’ is written as ‘NVMGZO’ in a certain code language then how will ‘SILVER’ be written in the same code language ?
(A) HROEVI (B) HORVEI (C) GROVEI (D) GOREVI
(E) None of these
Solution (A)
MENTAL NVMGZO
Reverse letter for M is N, for E it is V, for N it is M, for T it is G, for A it is Z and for L it is O. this is the rule applies in the word ‘MENTAL’.
Thus, the code word for ‘SILVER’ is obtained by applying the same rule.
Example 3.
If in a certain code ‘MASTER’ is written as ‘SAMRET’ then how will ‘CARROT’ be written in the same code ?
(A) ARMOTR (B) RCATRO (C) RACTOR (D) None of these
Answer with explanation (D)
As,
In the same way,
But this answer is not in any alternative.
Example 4.
If in a certain code ‘MANISH’ is written as ‘NZMRHS’, then how will ‘RANJITA’ be written in the same code ?
(A) IZMQRGZ (B) IZMPRGZ (C) IZMQRHZ (D) IZMQRIZ
Answer with explanation (A)
As,
Similarly,
Example 5.
If in a certain code ‘CANDLE’ is written as ‘FDQGOH’, then how will ‘MINUTE’ be written in the same code ?
Answer with explanation (D)
As,
Similarly,
Example 6.
If in a certain code ‘ Kit Mit Fit’ means ‘I an laborious’; ‘Zit Rit Kit’ means ‘Laborious is dangerous’ and ‘Sil Fis Kit’
means ‘Dangerous very troublous’ then which word in that code represents ‘Is’ ?
(A) Kit (B) Zit (C) Rit (D) None of these
Example 7.
In a certain code ‘345’ means ‘Veera is gentle’, ‘579’ means ‘Veera Kind Hearted’ and 126 means ‘Kanchan also good’
then which digit in that code represents ‘Gentle’ ?
(A) 3 (B) 4 (C) 5 (D) Cannot be decided
Answer with explanation (D)
Now, in (i) there are two digits and two words left. Now it is very difficult to decide which digits is used for ‘Gentle’.
Example 8.
If ‘Cloud’ is coded as ‘Rain’, ‘Rain’ is coded as ‘Tree’, ‘Tree’ is coded as ‘Axe’, ‘Axe’ is coded as ‘House’ and ‘House’
is coded as ‘Mason’ then from which wood is obtained ?
(A) Tree (B) Rain (C) Axe (D) None of these
Answer with explanation (C)
Wood is obtained from tree and tree is coded as ‘Axe’. Hence, wood is obtained from ‘Axe’.
