In each of the following questions, choose the number - letter group which is different from the others.

Options

A. OE3
B. XD6
C. JB5
D. PH3

Answer

To solve the problem, we need to analyze the given groups of letters and numbers to identify which group is different from the others.

### Step-by-Step Solution:

1. **Identify the Groups**: We have four groups:
- Group 1: O, E, 3
- Group 2: X, D, 6
- Group 3: J, B, 5
- Group 4: P, H, 3

2. **Find Corresponding Numbers for Letters**: Using the provided table:
- For O: 15
- For E: 5
- For X: 24
- For D: 4
- For J: 10
- For B: 2
- For P: 16
- For H: 8

3. **Write Down the Corresponding Values**:
- Group 1: O (15), E (5), 3 → Values: 15, 5, 3
- Group 2: X (24), D (4), 6 → Values: 24, 4, 6
- Group 3: J (10), B (2), 5 → Values: 10, 2, 5
- Group 4: P (16), H (8), 3 → Values: 16, 8, 3

4. **Check the Relationship Between Numbers**:
- For Group 1: 5 * 3 = 15 (True)
- For Group 2: 4 * 6 = 24 (True)
- For Group 3: 2 * 5 = 10 (True)
- For Group 4: 8 * 3 = 24 (Not equal to 16)

5. **Identify the Odd One Out**:
- The first three groups have a consistent relationship where the second number multiplied by the third number equals the first number.
- However, in Group 4, the relationship does not hold true (8 * 3 = 24, not 16).

### Conclusion:
The group that is different from the others is **Group 4: P, H, 3**.
