(Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)
Identifying the Odd Letter Cluster Using Alphabetical Order
The question asks us to find the letter-cluster that doesn't fit a pattern shared by the other three. The pattern is based on the alphabetical order of the letters within each cluster. We need to determine the relationship between the first, second, and third letters in each cluster.
Analyzing Letter Cluster Patterns
We will assign numerical values to each letter based on its position in the English alphabet (A=1, B=2, ..., Z=26). Then, we will examine the difference in positions between consecutive letters.
| Cluster | Letter 1 | Pos 1 | Letter 2 | Pos 2 | Letter 3 | Pos 3 | Step 1 (Pos1 → Pos2) | Step 2 (Pos2 → Pos3) |
|---|---|---|---|---|---|---|---|---|
| FBY | F | 6 | B | 2 | Y | 25 | F (6) to B (2): $6 - 2 = 4$. This is a backward step of 4. |
B (2) to Y (25): $2 - 25 = -23$. Considering the alphabet wraps around, stepping back 3 positions from B (2) lands on Y (25) (i.e., $2 \rightarrow 1 \rightarrow 26 \rightarrow 25$). So, this is a backward step of 3. |
| QMJ | Q | 17 | M | 13 | J | 10 | Q (17) to M (13): $17 - 13 = 4$. This is a backward step of 4. |
M (13) to J (10): $13 - 10 = 3$. This is a backward step of 3. |
| PMI | P | 16 | M | 13 | I | 9 | P (16) to M (13): $16 - 13 = 3$. This is a backward step of 3. |
M (13) to I (9): $13 - 9 = 4$. This is a backward step of 4. |
| OKH | O | 15 | K | 11 | H | 8 | O (15) to K (11): $15 - 11 = 4$. This is a backward step of 4. |
K (11) to H (8): $11 - 8 = 3$. This is a backward step of 3. |
Note: The 'Step' values represent the number of positions moved backward in the alphabet.
Identifying the Consistent Pattern
By examining the table, we can observe the sequence of backward steps for each cluster:
- FBY: The sequence of backward steps is (-4, -3).
- QMJ: The sequence of backward steps is (-4, -3).
- OKH: The sequence of backward steps is (-4, -3).
Three of the letter-clusters (FBY, QMJ, OKH) share the same pattern of backward steps: first moving 4 positions back, then moving 3 positions back.
Determining the Outlier
The letter-cluster PMI has a different sequence of backward steps:
- PMI: The sequence of backward steps is (-3, -4).
This sequence (-3, -4) does not match the common pattern (-4, -3) found in the other three clusters.
Conclusion
Therefore, the letter-cluster PMI is the one that does not belong to the group.
Important Questions from Classification (Notes)
- Find the odd one out
- Consider the following four words, out of which three are alike in some manner and one is different.
(A). Arrow
(B). Missile
(C). Sword
(D). Bullet
Choose the combination that has alike words. - Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which letter-cluster pair DOES NOT belong to that group?
