AFHO : GBDJ :: CHFM : ?

Options

A. GBIM
B. GBLD
C. GPLD
D. IDBH

Explanation

To solve the analogy problem AFHO : GBDJ :: CHFM : ?, we need to analyze the pattern in the first pair of letters (AFHO and GBDJ) and apply the same pattern to the second pair (CHFM).

### Step-by-Step Solution:

1. **Analyze the first pair (AFHO and GBDJ)**:
- A to G:
- A is the 1st letter of the alphabet.
- G is the 7th letter of the alphabet.
- The difference is 7 - 1 = 6 (move forward 6 steps).
- F to B:
- F is the 6th letter.
- B is the 2nd letter.
- The difference is 2 - 6 = -4 (move backward 4 steps).
- H to D:
- H is the 8th letter.
- D is the 4th letter.
- The difference is 4 - 8 = -4 (move backward 4 steps).
- O to J:
- O is the 15th letter.
- J is the 10th letter.
- The difference is 10 - 15 = -5 (move backward 5 steps).

2. **Determine the pattern**:
- The pattern observed is:
- First letter: +6
- Second letter: -4
- Third letter: -4
- Fourth letter: -5

3. **Apply the same pattern to the second pair (CHFM)**:
- C to ?:
- C is the 3rd letter.
- Applying +6: 3 + 6 = 9 (9th letter is I).
- H to ?:
- H is the 8th letter.
- Applying -4: 8 - 4 = 4 (4th letter is D).
- F to ?:
- F is the 6th letter.
- Applying -4: 6 - 4 = 2 (2nd letter is B).
- M to ?:
- M is the 13th letter.
- Applying -5: 13 - 5 = 8 (8th letter is H).

4. **Combine the results**:
- The resulting letters from the transformations are: I, D, B, H.

5. **Final answer**:
- Therefore, the answer to the analogy CHFM : ? is IDBH.
