Letter Coding Decoding
In this type, we deal with questions, in which the letters of a word are replaced by certain other letters according to a specific pattern/rule to form a code. You are required to detect the coding pattern/rule and answer the questions that follow, based on that coding pattern/rule.
In Random Letter Coding Decoding : the sequence will not follow a specific pattern of assigning numbers to alphabets. The pattern can be established by various ways but in every case a set of new pattern / principle is involved which has to be done carefully.
Example 1 : In a certain code, ‘EUROPEON’ is written as ‘TDNQDOMN’. Which of the following word will be coded as NBRMQDZUHSMN.?
(A) CONVERSATION (B) CONSERVATION (C) CONVARSATION (D) CONSRAVATION
Answer : (B)
Solution : In this question, we can identify the following relationship:
The word EUROPEON and APPROACH contains 8 letters.
EU = UE, subtract 1 from U and E,
U - 1 = T
E - 1 = D
RO = OR, subtract 1 from O and R
O - 1 = N
R - 1 = Q
PE = EP, subtract 1 from E and P
E - 1 = D
P - 1 = O
ON = NO subtract 1 from N and O
N - 1 = M
O - 1 = N
Similarly, in case of CONSERVATION.
CO = OC, O - 1 = N, C - 1 - B
NS= SN, S - 1 = R, N - 1 = M
ER = RE, R - 1 = Q, E - 1 = D
VA = AV, A - 1 = Z, V - 1 = U
TI = IT, I - 1 = H, T - 1 = S
ON = NO, N - 1 = M, O - 1 = N
So, the answer is NBRMQDZUHSMN.
Example 2 : In a certain code, ‘BELIEF’ is written as ‘AFKKDH’. How would ‘SELDOM’ be written in that code?
(A) RDKCHL (B) RFKENM (C) RFKFNO (D) TFKENP
Answer : (C)
Solution : In this question, we can identify the following relationship:
Now, apply this relation in the word "SELDOM":
Hence, the answer is RFKFNO.
Example 3 : In a certain code, ‘MOTHER’ is written as ‘KPRICS’. How would ‘CLOUDS’ be written in that code?
(A) RDKCHL (B) AMMVB (C) AMMTB (D) AMMVP
Answer : (B)
Solution : In this question, we can identify the following relationship:
Now, apply this relation in the word "CLOUD":
Hence, the answer is AMMVB.
Example 4 : In a certain code, ‘EXAMINATION’ is written as ‘HYDNLODULPQ’. How would ‘CORRECTION’ be written in that code?
(A) RDKCHLEFTG (B) FPUSRFWJRO (C) FPUSHDWJRO (D) FPUSHAMMVP
Answer : (C)
Solution : In this question, we can identify the following relationship:
Now, apply this relation in the word "CORRECTION":
Hence, the answer is FPUSHDWJRO
