In this question each alphabet is replaced with its number+1 in the order of alphabets as F=6+1
A=1+1
L=12+1
E=5+1
N=14+1
Similarly IMPAL is also coded as 101417213 and so code for LENIN is
L=12+1
E=5+1
N=14+1
I=9+1
N=14+1

In this question each alphabet is replaced with its number-1 in the order of alphabets as O=15-1
I=9-1
R=18-1
T=20-1
V=22-1
Similarly BFIPL is also coded as 1581511 and so code for LJGRE is
L=12-1
J=10-1
G=7-1
R=18-1
E=5-1

In this question each alphabet is replaced with its number in the order of alphabets as L=12
A=1
F=6
G=7
U=21
Similarly OTVLQ is also coded as 1520221217 and so code for BDRIU is
B=2
D=4
R=18
I=9
U=21

In this code
H=J-2
F=H-2
W=Y-2
Q=S-2
Z=B-2 similarly for AJYQU and so required code for SIXER is
P-2=N
O-2=M
W-2=U
Y-2=W
L-2=J
I.e NMUWJ

In this code
S=Q+2
M=K+2
C=A+2
K=I+2
V=T+2 similarly for VGHRS and so required code for SIXER is
B+2=D
H+2=J
A+2=C
S+2=U
R+2=T
I.e DJCUT

In this question each letter is replaced by its opposite letter i.e if B is 2nd letter from the beginning it is replaced by 2nd letter from the end i.e Y and whole code is reversed i.e
For HAJSU its reverse order alphabets are SZQHF and the answer is reversed i.e FHQZS
Similarly for “JAVGY” it is “QZETB” and its reverse is “BTEZQ”

In this question each letter is replaced by its opposite letter i.e if B is 2nd letter from the beginning it is replaced by 2nd letter from the end i.e Y
For OPERA it is LKVIZ and so for RAMBO it is IZNYL

In this code
B=A+1
K=L-1
U=T+1
D=E-1
S=R+1 similarly for DELIM and so required code for PROMT is
P+1=Q
R-1=Q
O+1=P
M-1=L
T+1=U
I.e QQPLU

In this code
K=L-1
G=I-2
P=S-3
P=T-4
Z=E-5
H=N-6
similarly for MOTHER and so required code for KITTEN is
K-1=J
I-2=G
T-3=Q
T-4=P
E-5=Z
N-6=H
I.e JGQPZH

In this code
L=K+1
K=I+2
D=A+3
V=R+4
F=A+5 similarly for KABIR and so required code for SIXER is
S+1=T
I+2=K
X+3=A
E+4=I
R+5=W
I.e TKAIW

In the code language odd places were replaced by next letter in the alphabet series and even places were replaced by letter before and so Y is replaced with Z
H is replaced with G
J is replaced with K
R is replaced with Q and similarly for IOLS
T is replaced with U
Y is replaced with X
G is replaced with H
F is replaced with E
So the correct answer is UXHE

In the code language odd places were replaced by next letter in the alphabet series and even places were replaced by letter before and so F is replaced with G
I is replaced with H
R is replaced with S
M is replaced with N and similarly for MEAL
M is replaced with N
E is replaced with D
A is replaced with B
L is replaced with K
So the correct answer is NBK

In this language each letter is replaced with its place value in alphabets in reverse order i.e for “FTU” it is “UTF” U=21,T=20,F=6 and similarly “JKR” as “RKJ” and so for DOZ it is ZOD we have Z=26,O=15, D=4 and so correct answer is 26154.

In this language each letter is replaced with its place value in alphabets in reverse order i.e for “KXL” it is “LXK” L=12,X=24,K=11 and similarly “NRT” as “TRN” and so for FIP it is PIF we have P=16,I=9, F=6 and so correct answer is 1696.

In this language each letter is replaced with its place value+1 in alphabets as A=1+1,N=14+1,U=21+1 and similarly RAM and so for KAV we have K=11+1,A=1+1, V=22+1 and so correct answer is 12223

In this language each letter is replaced with its place value+1 in alphabets as F=6+1,O=15+1,R=18+1 and similarly MAP and so for SPA we have S=19+1,P=16+1, A=1+1 and so correct answer is 20172

In this language each letter is replaced with its value in alphabets as L=12,E=5,T=20 and similarly HIM and so for PAN we have P=16, A=1,N=14 and so correct answer is 16114.

In this language each letter is replaced with its value in alphabets as V=22,I=9,M=13,A=1 and L=12 and similarly KILL and so for FULL we have F=6, U=21,L=12,L=12 and so correct answer is 6211212.

Let us write the alphabets from A to Z in two rows as shown below.

1            2             3             4             5             6             7             8               9            10            11          12           13

26          25           24            23             22            21           20           19            18           17           16           15          14

Given,

HUT = 3360

H = 8; U = 21; T = 20

HUT = $8 \times 21 \times 20 = 3360$

TAP is coded as 320

T = 20; A=1; P = 16

TAP = $20 \times 1 \times 16 = 320$

Similarly,

PUN = $16 \times 21 \times 14 = 4704$

Here the symbol $represents +, and the symbol # represents$\times$9 + 7$\times$6 = 51 12 + 7$\times$9 = 75$\therefore$23 + 6$\times\$ 7 = 65
