Question

F129 is related to TW49 in a certain way. In the same way, LO38 is related to ZC58. To which of the following is RU65 related, following the same logic?

• A. FE85
• B. IF58
• C. EF58
• D. FI85

Answer 1

Answer:

D. FI85

Let’s carefully correct the pattern.

Given:

F129 → TW49
LO38 → ZC58

Letter pattern

Check alphabetical shifts:

F → T

F = 6, T = 20
Difference = +14

W → F (next pair relation confirms reverse pairing idea)

So rule:
First letter +14, second letter -14 (with wrap around)

Number pattern

Check carefully:

129 → 49
129 - 80 = 49
38 → 58

38 + 20 = 58
]

So number rule depends on position, but pattern used consistently in such questions is:
middle transformation gives +20 or -80 depending on structure

Apply to RU65

Letters:

• R (18) → F (6)
  (18 − 12 = 6)

• U (21) → I (9)
  (21 − 12 = 9)

So letters become: FI

Numbers:

Using pattern consistency from second relation:

65 + 20 = 85

Final Answer:

FI85
