HAPPYBOYS ------------ SZKKBYLBH
Hence, Option C is correct.

Following common explanation we get “a – rx”.

Hence, Option C is correct.

Common explanation:

“Matching extinct a problem” is coded as “rx ik mq mp” ….(1)

“Problem is solved” is coded as “ik uz yj” ….(2)

1. The first letter of each code is obtained by shifting the first letter of the word by a certain number of positions in the alphabet.
2. The number in the code represents the alphabetical position of the last letter of the word.

Applying this pattern to "PIPES":

1. First letter: 'P' is the 16th letter of the alphabet. Shifting 'P' by -8 positions gives 'H' (8th letter).
2. Last letter: 'S' is the 19th letter of the alphabet, so the number part of the code remains 16.

Therefore, the code for "PIPES" is "H16".

Following common explanation we get “Solved – uz”.

Hence, Option D is correct.

Common explanation:

“Matching extinct a problem” is coded as “rx ik mq mp” ………….(1)

“Problem is solved” is coded as “ik uz yj” ……………….(2)

“Green is matching” is coded as “yj mp nt” ………………..(3)

“Extinct of oral” is coded as “mq vq jb” ……………………..(4)

From (1) and (2), we get:

Problem – ik ………………………………………….(5)

From (1) and (3), we get:

Matching – mp ……………………………………..(6)

From (1) and (4), we get:

Extinct – mq …………………………………………(7)

From (1), (5), (6) and (7), we get:

a – rx ………………………………………………….(8)

From (2) and (3), we get:

is – yj ………………………………………………(9)

From (2), (5) and (9), we get:

Solved – uz ……………………………………..(10)

From (3), (6) and (9), we get:

 Green – nt …………………………….(11)

From (1) and (4), we get:

Of / oral – vq / jb …………………….(12)

Following the common explanation we get the “matching – mp, of – vq/jb”.

Thus possible code is mp vq or mp jb.

Hence, Option E is correct.

Common explanation:

“Matching extinct a problem” is coded as “rx ik mq mp” …………….(1)

“Problem is solved” is coded as “ik uz yj” …………….(2)

“Green is matching” is coded as “yj mp nt” ……..(3)

“Extinct of oral” is coded as “mq vq jb” ………………..(4)

From (1) and (2), we get:

Problem – ik ………………………………………….(5)

From (1) and (3), we get:

Matching – mp ……………………………………..(6)

From (1) and (4), we get:

Extinct – mq …………………………………………(7)

From (1), (5), (6) and (7), we get:

a – rx ………………………………………………….(8)

From (2) and (3), we get:

is – yj ………………………………………………(9)

From (2), (5) and (9), we get:

Solved – uz ……………………………………..(10)

From (3), (6) and (9), we get:

 Green – nt …………………………….(11)

From (1) and (4), we get:

Of / oral – vq / jb …………………….(12)

Logic: Opposite letter of last letter and the place value of first letter.

So, the code for Time is V20.

Hence, Option D is correct.

M18 – The place value of R is 18 and the N is opposite of M.

So, the possible word for M18 will have starting letter as R and ending letter as N. Only one option is there that matches i.e, Risen.

Hence, Option D is correct.

SOBER is written as RNADQ.
in RNADQ. every letter is 1 previous of SOBER 
K comes before L
N comes before O
S comes before T
T comes before U
R comes before S

This way KNSTR is correct option

Move two letter backward (-2)
if we move two letter back after H it comes F.
if we move two letter back after K it comes I.
if we move two letter back after I it comes R.
if we move two letter back after G it comes E.

Move +2,+3,+4 forward for first 3 letters
Move -2,-3,-4 backward for last 3 letters

C +2 = E
A + 3 = D
S + 4 = W
K - 2 = I
E - 3 = B
T - 4 = P

So The answer is EDWIBP

If P means #,A means %,C means $ and E means@
So,
P ⇒ #
E ⇒ @
A ⇒ %
C ⇒ $
E ⇒ @

So the code for PEACE will be #@%$@

From question it is clear that each alphabet has a code based on their alphabetical order. For example a=1, b=2 ....z=26.

by going through options
l ⇒ 12
o ⇒ 15
v ⇒ 22
e ⇒ 5

so code for 1215225 is love.

So, the code for "Out" is ka.

But 'out' is not given in the solution, so the answer is "None of these".

Hence, the correct answer is "option (4)".
