Two sets of numbers are given below. In each set of numbers, certain mathematical operation(s) on the first number result(s) in the second number. Similarly, certain mathematical operation(s) on the second number result(s) in the third number and so on. Which of the given options follows the same set of operations as in the given sets?
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct Answer:
D. 22 – 23 – 27 – 36
Explanation:
The logic follows a pattern where each letter in the first word is shifted backward by 4 positions in the English alphabet to create the second word.
Applying this to the example SKIB to OGNG:
S - 4 = O
K - 4 = G
I - 4 = E (Note: The example OGNG seems to contain a typo for OGNE, but the shift of 4 is consistent across CUCV to YQHA)
Applying this to CUCV to YQHA:
C - 4 = Y
U - 4 = Q
C - 4 = Y (Note: The example YQHA seems to contain a typo for YQYS, but following the logic of C to Y)
V - 4 = R (Note: Following the shift pattern)
Applying a consistent -4 shift logic to QIRK:
Q - 4 = M
I - 4 = E
R - 4 = N (Note: If the pattern is -4, -2, -4, -2)
K - 4 = G
However, looking at the provided options (MWEP, MWPE, MEPW, MEWP), the shift follows a pattern of -4, +14 (or -12), -4, +5. Specifically for QIRK:
Q - 4 = M
I + 14 = W
R - 4 = N (or I to E is -4)
K + 5 = P
By analyzing the shifts between QIRK and the options:
Q shifted by -4 is M.
I shifted by -4 is E.
R shifted by -4 is N.
K shifted by -4 is G.
Since MENG is not an option, and evaluating the shifts for MEWP:
Q - 4 = M
I - 4 = E
R + 5 = W
K + 5 = P
The most logical choice based on the structure of the options is MEWP.
