Understanding the Letter Cluster Pattern

This question involves finding a specific rule for rearranging letters within a word (a letter cluster). We need to figure out how COLOUR changes to CUOLOR and how TRIBAL changes to TABIRL. Once we understand this pattern, we apply it to FINGER to find the correct option.

Analyzing the First Pair: COLOUR to CUOLOR

Let's look closely at the transformation from COLOUR to CUOLOR.

Original Word: COLOUR

Transformed Word: CUOLOR

We can assign numbers to the positions of the letters in COLOUR:

• C is at position 1
• O is at position 2
• L is at position 3
• O is at position 4
• U is at position 5
• R is at position 6

Now, let's see how these original positions are mapped in the transformed word CUOLOR:

• The 1st letter (C) stays in the 1st position.
• The 5th letter (U) moves to the 2nd position.
• The 4th letter (O) moves to the 3rd position.
• The 3rd letter (L) moves to the 4th position.
• The 2nd letter (O) moves to the 5th position.
• The 6th letter (R) stays in the 6th position.

This transformation can be described by the sequence of original positions that form the new word. The pattern is: the 1st letter, then the 5th, then the 4th, then the 3rd, then the 2nd, and finally the 6th. We can represent this permutation of indices as (1, 5, 4, 3, 2, 6).

Analyzing the Second Pair: TRIBAL to TABIRL

To confirm our pattern, let's check if it works for the second pair: TRIBAL transforming into TABIRL.

Original Word: TRIBAL

Transformed Word: TABIRL

Applying the positional pattern (1, 5, 4, 3, 2, 6) to TRIBAL:

• Position 1 (T) stays at position 1.
• Position 5 (A) moves to position 2.
• Position 4 (B) moves to position 3.
• Position 3 (I) moves to position 4.
• Position 2 (R) moves to position 5.
• Position 6 (L) stays at position 6.

Combining these letters results in T A B I R L, which perfectly matches the given transformation TABIRL. Our pattern is confirmed.

Applying the Pattern to FINGER

Now, we use the confirmed pattern (1, 5, 4, 3, 2, 6) to find the transformation for FINGER.

Original Word: FINGER

Let's identify the letters by their positions:

• F is at position 1
• I is at position 2
• N is at position 3
• G is at position 4
• E is at position 5
• R is at position 6

We rearrange these letters according to the pattern (1, 5, 4, 3, 2, 6):

• The 1st letter is F (from original position 1).
• The 2nd letter is E (from original position 5).
• The 3rd letter is G (from original position 4).
• The 4th letter is N (from original position 3).
• The 5th letter is I (from original position 2).
• The 6th letter is R (from original position 6).

Putting these together, we get the transformed word: FEGNIR.

Conclusion

The letter cluster related to FINGER, following the same logic as the previous examples, is FEGNIR. This result matches option 3.
