Answers & Solutions:
1) Answer (C)
The code uses the letters in the alphabetical series in an inverted fashion. For example: A is used in the place of Z, B in the place of Y, etc. Also they are inverted. So, The last letter comes first in the code. So, I is replaced with R, K with P, M with N and O with L. The code is LNPR.
2) Answer (A)
The common word in the first and second scripts is Rani which is therefore coded as mo. The second and third scripts have to have a common word in their codes ( of) but not mo. So, option a is the right answer.

e and a are represented by 3 and 4. l and p are represented by 7 and 8 (only present in the last word ie help).
So, the required word is leap.
5) Answer (C)
6) Answer (C)
M – 2 = J
O + 2 = R
T -2 = Q
H + 2 =K
E – 2 = B
R + 2 = U
Following the same logic , PRINCIPAL will be MUFQZLMDI.
So, the answer would be option c)MUFQZLMDI
7) Answer (D)
you are john’ ….. ‘net let fat’.(1)
‘who are you’ ….. ‘let wet net’ (2)
‘John is good’ ….. ‘get set fat (3)

The followed pattern is:
and,
Hence, KNIFE will be written as IKEAY.
9) Answer (C)
39574 is written as XPLMD, and 0826 as TBNQ
DBMTX=48703
10) Answer (D)
SIGN is coded as 8367 and DIRECT is coded as 134259
S=8 D=1
I=3 I=3
G=6 R=4
N=7 E=2
C=5
T=9
SIREN=83427
