Tech Mahindra Coding decoding Quiz 1

Since the example represents the reverse arrangement of same words, it is ought to followed the same pattern in the answer as well.
Therefore, rearranging ORPHAN brings up the result as NAHPRO in the answer.

For the example provided, every letter of TABLE skips two middle alphabetical letters to obtain WDEOH.
Similarly, to obtain the code of POOR,
For P, skipping middle two alphabetical letters, the result obtained is S.
For O, skipping middle two alphabetical letters, the result obtained is R.
Again for O, skipping middle two alphabetical letters, the result obtained is R.
For R, skipping middle two alphabetical letter, the result obtained is U.
Therefore, the answer is SRRU.

In the given word, it follows a specific pattern to generate the next word. In the word STANZA,
S – T (T is the succeeding letter of S).
T – S (S is the preceding letter of T).
A – B (B is the succeeding letter of A).
N – M (M is the preceding letter of N).
Z – A (A is the succeeding letter of Z).
A – Z (Z is the preceding letter of A).
The same pattern works for PARA.
P – Q (Q is the succeeding letter of P).
A – Z (Z is the preceding letter of A).
R – S (S is the succeeding letter of R).
A – Z (Z is the preceding letter of A).
Therefore, the correct answer is QZSZ.

W(23) A(1) T(20) E(5) R(18) U (21) N(14) I(9) V(22) E(5) R(18) S(19) E(5)
+4        -4        +4      -4      +4     +4        -4       +4      -4     +4      -4     +4     -4
A(1) W(23) X(24) A(1) V(22) Y(25) J(10) M(13) R(18) I(9) N(14) W(23) A(1)

M    A    X    I    M    U    M    T    R    A    V    E    L
13     1   24   9    13   21   13   20  18    1    22   5   18

T    R    A    V    E    L

20 18    1   22    5    18

Each letter is written in a cross with +1 following this
rule we get THOR as IUSR

If we check the alphabets we found that it follows
the pattern of -1, +2, +4 and + 8 in cross.
Thus chemical can be coded as GBOGGMTI.

Center letter is same and other are exchanged
G=R
R=G
A=A
N=D
D=N
Similarly NOBLE is ONBEL

M=13-1=12=2unit digit
U=21-1=20=0
M=13-1=12=2
B=2-1=1
A=1-1=0
I=9-1=8
Similarly DELHI=34178

S – 2 = P H – 2 = E I – 2 = F R – 2 =O T – 2 =Q Similarly PAINT=MXFKQ
