TOUR → 1234
CLEAR → 56784
SPARE → 90847

Common alphabets in the three words are: 
(i) R coded with the number 4 in each word.
(ii) E coded with the number 7 in each word.
(iii) A coded with the number 8 in each word. 

It is clear from here that each alphabet represents a particular number/code.

In the word, SCULPTURE the 5th digit is P and in the above-given words, P is coded with the number 0.

B + 1 = C
A - 1 = Z
N + 1 = O
G - 1 = F
A + 1 = B
L - 1 = K
O + 1 = P
R - 1 = Q
E + 1 = F
BANGALORE → CZOFBKPQF

Similarly,
C +1 = D
A - 1 = Z
L + 1 = M
C - 1 = B
U + 1 = V
T - 1 = S
T + 1 = U
A - 1 = Z
CALCUTTA → DZMBVSUZ

Every letter is interchanged by its subsequent second letter.
i.e. POSTPONE → OPTSOPEN

Therefore, RAJASTAN → ARAJTSNA

In the code, first three letters are reversed, EXP → PXE
then next two letters, LA → AL
then again next two letters, IN → NI
finally the last three letters are reversed, ING → GNI
Resulting: EXPLAINING → PXEALNIGNI

Similarly,
PRODUCTION → ORPUDTCNOI

TEACHING:CHEATING ⇔ 12345678:45231678 

BANKING:? ⇔ 12345678:45231678

Thus, BANKINGS will become KIANBNGS

F - 2 = D
I - 2 = G
R - 2 = P
E - 2 = C
FIRE →DGPC

Similarly,
S - 2 = Q
H - 2 = F
O - 2 = M
T - 2 = R
QFMR → SHOT.

Hence, the last letter of the coded word is R.

A - 1 = Z
W - 1 = V
A - 1 = Z
K - 1 = J
E - 1 = D
AWAKE → ZVZJD

Similarly, 
F - 1 = E
R - 1 = Q
I - 1 = H
E - 1 = D
N - 1 = M
D - 1 = C
FRIEND → EQHDMC

PAINT - 74128
EXCEL - 93596
Since each letter is assigned a unique code in the given words.
Therefore, the code for ACCEPT is 455978.

Write the letters of the given word in reverse order
i.e. LOGIC → CIGOL
Now write the previous letters of the reversed word
i.e. CIGOL → BHFNK

Similarly, 
CLERK → KRELC→ JQDKB

L - 5 = G
M - 5 = H
N - 5 = I
O - 5 = J
LMNO → GHIJ

Similarly,
S - 5 = N
T - 5 = O
U - 5 = P
V - 5 = Q
STUV → NOPQ

TOUR → 1234
CLEAR → 56784
SPARE → 90847

Common alphabets in the three words are: 
(i) R coded with the number 4 in each word.
(ii) E coded with the number 7 in each word.
(iii) A coded with the number 8 in each word. 

It is clear from here that each alphabet represents a particular number/code.

Using the codes for the letter from given words.
C A R E will become 5 8 4 7

Here you can see the vowels are not changing, only consonants are changing and they are also changing in the order of -1,-1,-2 

Thus,
DONE AT GATV AT ZOU DAP ⇒ COME AS FAST AS YOU CAN

Letters of the word PREMONITION are coded as follows:

Letters → Code
P → 6
R → 8
E → 5
M → 3
O → 0
N → 4
I → 9
T → 2
I → 9
O → 0
N → 4

Therefore, code for the word MONITOR is 3049208

Arrange the word in alphabetical order and compare the pair obtained in the word and in the alphabet. The number of letters between should be equal in both. Here, the pairs obtained from the word SEQUENTIAL are SN, SQ, QN SA, and EA. Hence, five is the answer
