What should come in place of the question mark (?) in the given series based on the English alphabetical order?- GUR, QEB, AOL, KYV,  ?

Solution:

Let’s look at each position of the letters separately.

Given series:
GUR, QEB, AOL, KYV, ?

Step 1: First letters

G (7), Q (17), A (1), K (11)

Pattern:
+10 (7 → 17), +10 (17 → 27 → 1), +10 (1 → 11)

So next: 11 + 10 = 21 → U

Step 2: Second letters

U (21), E (5), O (15), Y (25)

Pattern:
+10 each time (with wrap around)

So next: 25 + 10 = 35 → 35 − 26 = 9 → I

Step 3: Third letters

R (18), B (2), L (12), V (22)

Pattern:
+10 each time (with wrap around)

So next: 22 + 10 = 32 → 32 − 26 = 6 → F

Final term:

U I F → UIF

Final Answer: d. UIF
