Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster DOES NOT belong to that group?
(Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)
Letter Cluster Reasoning: Identifying the Odd One Out
This question requires us to identify the letter cluster that doesn't follow the same logical pattern as the others. We need to analyze the relationship between the letter pairs in each option based on the English alphabetical order.
Analyzing the Alphabetical Pattern
We will assign numerical positions to each letter (A=1, B=2, ..., Z=26) and examine the difference between the letters in the given pairs. The key is to find a consistent pattern connecting three of the options.
Step 1: Assign Numerical Positions
Let's list the positions for the letters in each option:
- Option 1: $KS - HO$ -> K(11), S(19); H(8), O(15)
- Option 2: $MQ - JM$ -> M(13), Q(17); J(10), M(13)
- Option 3: $XB - UX$ -> X(24), B(2); U(21), X(24)
- Option 4: $TE - PB$ -> T(20), E(5); P(16), B(2)
Step 2: Calculate Differences Between Corresponding Letters
Now, let's find the difference between the first letter of the first pair and the first letter of the second pair, and similarly for the second letters. We are looking for a pattern based on alphabetical order (moving backward).
| Option | Cluster Pair | First Letter Difference | Second Letter Difference | Observed Pattern |
|---|---|---|---|---|
| 1 | $KS - HO$ | K(11) to H(8) = $11 - 8 = 3$ | S(19) to O(15) = $19 - 15 = 4$ | Difference of 3, Difference of 4 |
| 2 | $MQ - JM$ | M(13) to J(10) = $13 - 10 = 3$ | Q(17) to M(13) = $17 - 13 = 4$ | Difference of 3, Difference of 4 |
| 3 | $XB - UX$ | X(24) to U(21) = $24 - 21 = 3$ | B(2) to X(24) = (Consider wrap around: $2 - 4 = -2 \equiv 24 \pmod{26}$) = 4 | Difference of 3, Difference of 4 |
| 4 | $TE - PB$ | T(20) to P(16) = $20 - 16 = 4$ | E(5) to B(2) = $5 - 2 = 3$ | Difference of 4, Difference of 3 |
Step 3: Identify the Odd One Out
By analyzing the differences:
- Options 1, 2, and 3 show a consistent pattern where the first letter pair has a difference of 3 (alphabetically backward) and the second letter pair has a difference of 4 (alphabetically backward).
- Option 4 shows a different pattern: the first letter pair has a difference of 4 (backward), and the second letter pair has a difference of 3 (backward).
Therefore, the letter cluster $TE - PB$ does not belong to the group.
