Finding the Odd Letter Cluster Pair

The question asks us to identify the letter-cluster pair that is different from the others based on a certain pattern. We need to examine how the letters in the first cluster of each pair are rearranged to form the second cluster.

Analyzing Each Letter Cluster Pair

Pair 1: TUKS : SKUT

• The first cluster is TUKS.
• The second cluster is SKUT.
• Let's look at the position of letters:

The second cluster SKUT is formed by reversing the order of the letters in the first cluster TUKS (S comes first, then K, then U, then T).

Pair 2: LKJR : RJKL

• The first cluster is LKJR.
• The second cluster is RJKL.
• Let's look at the position of letters:

The second cluster RJKL is formed by reversing the order of the letters in the first cluster LKJR (R comes first, then J, then K, then L).

Pair 3: PSRB : SRPB

• The first cluster is PSRB.
• The second cluster is SRPB.
• Let's look at the position of letters:

The second cluster SRPB is formed by rearranging the letters of PSRB in a specific order: the 2nd letter (S), then the 3rd letter (R), then the 1st letter (P), and finally the 4th letter (B). The order of letters is not simply reversed.

Pair 4: GMDI : IDMG

• The first cluster is GMDI.
• The second cluster is IDMG.
• Let's look at the position of letters:

The second cluster IDMG is formed by reversing the order of the letters in the first cluster GMDI (I comes first, then D, then M, then G).

Identifying the Pattern and the Odd One Out

Comparing the patterns observed:

• Pair 1 (TUKS : SKUT) follows the pattern: Reverse the letters.
• Pair 2 (LKJR : RJKL) follows the pattern: Reverse the letters.
• Pair 3 (PSRB : SRPB) follows the pattern: Rearrange letters as 2nd, 3rd, 1st, 4th.
• Pair 4 (GMDI : IDMG) follows the pattern: Reverse the letters.

Pairs 1, 2, and 4 all follow the same rule of reversing the order of the letters from the first cluster to get the second cluster. Pair 3 follows a different rule of rearrangement.

Therefore, the letter-cluster pair PSRB : SRPB is the odd one out.

Additional Information on Letter Series and Patterns

Questions involving letter clusters and pairs often test your ability to identify patterns based on:

• Position of letters: Rearranging letters based on their initial position, as seen in this problem (reversal or specific permutation).
• Alphabetical position: Patterns based on the position of letters in the English alphabet (e.g., adding or subtracting a certain number from the letter's position, skipping letters).
• Sequence/Series: Identifying a progression or sequence in the letters.
• Consonants/Vowels: Patterns based on whether letters are vowels or consonants.
• Mathematical operations: Sometimes involving simple arithmetic related to letter positions.

Practicing different types of letter pattern questions helps improve logical reasoning and problem-solving skills for competitive exams.
