LETTER CODING DECODING: Coding with Backward Sequence
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
LETTER CODING DECODING: Coding with Backward Sequence : This is the pattern of coding which exhibits the natural correlation of Arabic numbers with alphabetic letters. For instance, alphabets A to Z are assigned the numeric codes from 1 to 26 in the reverse order like A = 26, B = 25 and so on.
NOTE : Backward order position of a letter = 27 − Forward order position of letter
For Example : Backward order position of E = 27 − Forward order position of E = 27 −52 = 22
Example 1: In a certain code, TROPICAL is written as RPMNGAYJ . How would ‘ECOSYSTEM’ be written in that code?
(A) CAMQWRRCK (B) ) CAMQWQRCK (C) ) CANQWQRCK (D) ) CAMQXQRCK
Answer : (b)
Solution : In this question, we can identify the following relationship:
T - 2 = R
R - 2 = P
O - 2 = M
P - 2 = N
I - 2 = G
C - 2 = A
A - 2 = Y
L - 2 = J
Now, apply this relation in the word :
E - 2 = C
C - 2 = A
O - 2 = M
S - 2 = Q
Y - 2 = W
S - 2 = Q
T - 2 = R
E - 2 = C
M - 2 = K
Hence the answer is CAMQWQRCK.
Example 2 : In a certain code, ‘DECIDUOUS’ is coded as ‘ABZFARLRP’. Which words from the following would be coded as ‘BSBODOBBK’?
(A) EVRGREEN (B) EVERGREEN (C) GREENEVER (D) EVERGEERN
Answer : (B)
Solution : In this question, we can identify the following relationship:
D - 3 = A
E - 3 = B
C - 3 = Z
I - 3 = F
D - 3 = A
U - 3 = R
O - 3 = L
U - 3 = R
S - 3 = 16
Now, apply this relation in the word :
E - 3 = B
V - 3 = S
E - 3 = B
R - 3 = O
G - 3 = D
R - 3 = O
E - 3 = B
E - 3 = B
N - 3 = K
Hence, the correct option is EVERGREEN.
Example 3 : In a certain code, CROP is coded as CQOO . Which of the following is the coded of PRODUCTION ?
(A) PQOCUBTHON (B) POQUCBTHOM (C) PQOCUBTHOM (D) QQOCUBTHOM
Answer : (C)
Solution : In this question, we can identify the following relationship:
C - 0 = C
R - 1 = Q
O -0 = O
P - 1 = O
Now, apply this relation in the word :
P - 0 = P
R - 1 = Q
O - 0 = O
D - 1 = C
U - 0 = U
C - 1 = B
T - 0 = T
I - 1 = H
O - 0 = O
N - 1 = M
Hence, the correct option is PQOCUBTHOM.
Example 4 : In a certain code, MICROORGANISMS is coded as KFAOMLPDYKGPKP. Which of the following is the coded of CONSERVATION ?
(A) ALLPCOTXRFMK (B) ALLPCTXORFMK (C) ALLPCOTBMFK (D) ALLPTOAXRFMK
Answer : (A)
Solution : In this question, we can identify the following relationship:
M -2 = K
I - 3 = F
C - 2 = A
R - 3 = O
O - 2 = M
O - 3 = L
R - 2 = P
G - 3 = D
A -2 = Y
N- 3 = K
I - 2 = G
S - 3 = P
M - 2 = K
S - 3 = P
Now, apply this relation in the word :
C - 2 = A
O - 3 = L
N - 2 = L
S - 3 = P
E - 2 = C
R - 3 = O
V - 2 = T
A - 3 = X
T - 2 = R
I - 3 = F
O - 2 = M
N - 3 = K
Hence, the correct option is ALLPCOTXRFMK
Example 5 : In a certain code,AGRICULTURE is coded as VBMDXPGOPMZ. Which of the following is the coded of IMPROVEMENT?
(A) DKHJMQZHZIO (B) ) DHKMJQZHZIO (C) ) DHHIKQZHZIO (D) ) DHKMIZZHZIO
Answer : (B)
Solution : In this question, we can identify the following relationship:
A - 5 = V
G - 5 = B
R - 5 = M
I - 5 = D
C - 5 = X
U - 5 = P
L - 5 = G
T - 5 = 15
U - 5 = P
R - 5 = M
E - 5 = Z
Now, apply this relation in the word :
I - 5 = D
M - 5 = H
P - 5 = K
R - 5 = M
O - 5 = J
V - 5 = Q
E - 5 = Z
M - 5 = H
E - 5 = Z
N - 5 = I
T - 5 = O
Hence, the correct option is DHKMJQZHZIO
