There are a certain relationship between the left pair of alphabets. Establish the same relationship in the right pair and find the missing term.
AG : IO :: ? : MS

Options

A. EJ
B. DK
C. DJ
D. EK

Answer

To solve the problem, we need to establish the relationship between the pairs of letters provided and apply the same relationship to find the missing term.

### Step-by-Step Solution:

1. **Identify the Position of Letters in the Alphabet:**
- A = 1
- G = 7
- I = 9
- O = 15
- M = 13
- S = 19

2. **Analyze the First Pair (AG : IO):**
- The difference between the positions of A and G:
- G (7) - A (1) = 6
- The difference between the positions of I and O:
- O (15) - I (9) = 6
- Thus, the relationship between the first pair is that the second letter is 6 positions ahead of the first letter.

3. **Analyze the Second Pair (? : MS):**
- We need to find a letter that has the same relationship with MS.
- M (13) and S (19):
- The difference between S and M:
- S (19) - M (13) = 6
- Therefore, we need to find a letter (let's call it X) such that:
- X + 6 = M
- X = M - 6
- X = 13 - 6 = 7

4. **Identify the Letter Corresponding to Position 7:**
- The letter corresponding to position 7 is G.

5. **Conclusion:**
- Therefore, the missing term is G.
- The complete relationship is AG : IO :: G : MS.

### Final Answer:
The missing term is **G**.
