In each of the following questions, four groups of letters are given, three of them are alike in a certain way while one is different. Choose the odd one.

Options

A. EBD
B. IFH
C. QNO
D. YVX

Answer

To solve the problem, we need to analyze the given groups of letters and identify the one that does not follow the same pattern as the others.

### Step-by-Step Solution:

1. **Identify the Groups**: We have four groups of letters:
- Group 1: E, B, D
- Group 2: I, F, H
- Group 3: Q, O, N
- Group 4: Y, V, X

2. **Analyze Group 1 (E, B, D)**:
- To go from E to B:
- E (5) to B (2) = 3 steps back.
- To go from B to D:
- B (2) to D (4) = 2 steps forward.
- Pattern: 3 steps back, then 2 steps forward.

3. **Analyze Group 2 (I, F, H)**:
- To go from I to F:
- I (9) to F (6) = 3 steps back.
- To go from F to H:
- F (6) to H (8) = 2 steps forward.
- Pattern: 3 steps back, then 2 steps forward.

4. **Analyze Group 3 (Q, O, N)**:
- To go from Q to O:
- Q (17) to O (15) = 2 steps back.
- To go from O to N:
- O (15) to N (14) = 1 step back.
- Pattern: 2 steps back, then 1 step back.

5. **Analyze Group 4 (Y, V, X)**:
- To go from Y to V:
- Y (25) to V (22) = 3 steps back.
- To go from V to X:
- V (22) to X (24) = 2 steps forward.
- Pattern: 3 steps back, then 2 steps forward.

6. **Compare Patterns**:
- Groups 1, 2, and 4 all follow the same pattern of 3 steps back and then 2 steps forward.
- Group 3 follows a different pattern of 2 steps back and then 1 step back.

7. **Conclusion**: The odd one out is Group 3: Q, O, N.

### Final Answer:
The odd one out is **Q, O, N**.
