The correct answer is

EHGJ

Understanding Letter Cluster Analogies

Letter cluster analogies test your ability to find the relationship or pattern between a pair of letter clusters and apply that same pattern to a new letter cluster to find the missing one. In this question, we are given the analogy MNOP: LONQ :: FGHI : ?. We need to figure out how MNOP changes to LONQ and apply the same rule to FGHI.

Analyzing the First Letter Cluster Pair: MNOP to LONQ

Let's look at how each letter in MNOP relates to the corresponding letter in LONQ based on their positions in the alphabet.

  • The first letter M becomes L. In the alphabet, L comes just before M. This is a shift of -1 position.
  • The second letter N becomes O. In the alphabet, O comes just after N. This is a shift of +1 position.
  • The third letter O becomes N. In the alphabet, N comes just before O. This is a shift of -1 position.
  • The fourth letter P becomes Q. In the alphabet, Q comes just after P. This is a shift of +1 position.

So, the pattern observed from MNOP to LONQ is a sequential shift of -1, +1, -1, +1 for each letter.

Letter in MNOP Position Shift Resulting Letter in LONQ Position
M 13 -1 L 12
N 14 +1 O 15
O 15 -1 N 14
P 16 +1 Q 17

Applying the Pattern to FGHI

Now, we apply the same -1, +1, -1, +1 shift pattern to the letters in FGHI to find the missing letter cluster.

  • The first letter F gets a -1 shift. The letter before F is E.
  • The second letter G gets a +1 shift. The letter after G is H.
  • The third letter H gets a -1 shift. The letter before H is G.
  • The fourth letter I gets a +1 shift. The letter after I is J.

Combining the resulting letters, we get EHGJ.

Letter in FGHI Position Shift Resulting Letter Position
F 6 -1 E 5
G 7 +1 H 8
H 8 -1 G 7
I 9 +1 J 10

Conclusion

Following the pattern (-1, +1, -1, +1) observed in the first pair (MNOP: LONQ), applying it to FGHI results in the letter cluster EHGJ. Therefore, FGHI : EHGJ.

Revision Table: Understanding Letter Patterns

Original Letter Transformation Pattern Resulting Letter Example (MNOP > LONQ) Example (FGHI > EHGJ)
1st Letter -1 Position Letter before M > L F > E
2nd Letter +1 Position Letter after N > O G > H
3rd Letter -1 Position Letter before O > N H > G
4th Letter +1 Position Letter after P > Q I > J

Additional Information: Solving Letter Analogy Questions

Letter analogy and letter cluster questions are common in reasoning sections of exams. To solve them effectively, consider these strategies:

  • Alphabet Position: Write down the alphabet and their numerical positions (A=1, B=2, ..., Z=26). This helps in identifying shifts easily.
  • Look for Patterns: Check for sequential shifts (+1, -1, +2, -2, etc.), alternate letter shifts (1st to 3rd, 2nd to 4th, etc.), reverse order, skipping letters, or vowel/consonant patterns.
  • Practice: Solving various types of letter series and analogy problems helps in recognizing common patterns quickly.
  • Break Down the Problem: Compare letter by letter between the given pair to find the specific rule applied.
