Select the option that is related to the fifth letter-number cluster in the same way as the second letter-number cluster is related to the first letter-number cluster and fourth letter-number cluster is related to third letter-number cluster.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 - Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
TL210 : JV105 :: EK320 : IG160 :: DL500 : ?
Show answer & explanation
Correct answer: C
Explanation
Answer: JF250
Pattern logic:
Numbers: In each pair, the number simply halves.
- 210 → 105 (half)
- 320 → 160 (half)
- 500 → 250 (half)
Letters: Take the two letters as alphabet positions. The rule is:
Output = (2nd letter − 2, 1st letter + 2) — i.e., swap order, subtract 2 from the second letter, add 2 to the first letter.
Check with TL → JV:
T = 20, L = 12
→ (L−2, T+2) = (10, 22) = J, V ✔️
Check with EK → IG:
E = 5, K = 11
→ (K−2, E+2) = (9, 7) = I, G ✔️
Apply to DL → ?
D = 4, L = 12
→ (L−2, D+2) = (10, 6) = J, F
So DL500 → JF250
✅ Correct option: JF250
