In this letter analogy, “AGN is to IOV as BLM is to ______”. Select the group of letters that completes the analogy by applying the same fixed alphabet shift used in the first pair.

Introduction / Context:
This is a straightforward letter coding analogy. The pair “AGN : IOV” suggests that each letter in AGN has been shifted a fixed number of positions forward in the alphabet to obtain IOV. We need to identify that shift and then apply the same rule to the second group BLM, finally matching the output to one of the options. This type of analogy tests your ability to work with alphabetical positions quickly and accurately.

Given Data / Assumptions:

• Example mapping: AGN → IOV. • Target mapping: BLM → ? • Options: JTU, KTU, JUV, TUJ. • We use standard alphabet positions: A = 1, B = 2, ..., Z = 26 and wrap around if needed.

Concept / Approach:
We examine how each letter in AGN moves to the corresponding letter in IOV. If the difference in positions is the same for all three letters, then a single constant shift is being used. Once that shift is found, we apply it to each letter of BLM. The correct answer will be the option that exactly matches the resulting sequence of letters in the correct order.

Step-by-Step Solution:
Step 1: Convert AGN and IOV to numeric positions. A = 1, G = 7, N = 14. I = 9, O = 15, V = 22. Step 2: Find the shifts from AGN to IOV. 1 → 9: +8. 7 → 15: +8. 14 → 22: +8. So each letter is shifted forward by +8 positions. Step 3: Apply the same shift to BLM. B = 2, L = 12, M = 13. 2 + 8 = 10 → J. 12 + 8 = 20 → T. 13 + 8 = 21 → U. Step 4: The resulting group is JTU.

Verification / Alternative check:
We can check by reversing the shift. Subtracting 8 from each letter in IOV returns AGN: I (9) − 8 = A (1), O (15) − 8 = G (7), V (22) − 8 = N (14). Applying the same reverse operation to JTU gives BLM: J (10) − 8 = B (2), T (20) − 8 = L (12), U (21) − 8 = M (13). This confirms that the +8 mapping works consistently in both directions and that JTU is the only correct answer.

Why Other Options Are Wrong:
• KTU and JUV: These options change one or more letters in ways that do not match a constant +8 shift for BLM. • TUJ: Contains the same letters as JTU but in a different order. Analogies require both the correct letters and the correct positions.

Common Pitfalls:
Some test takers recognise that the letters J, T, and U are involved but choose an option where the order is wrong. Others detect a forward shift but miscount positions or forget to confirm the pattern works for all letters in the example pair, not just one letter. Careful, position by position checking is the safest way to handle such questions.

Final Answer:
The group of letters that correctly completes the analogy is JTU.
