Let’s solve step by step:

- The arrangement is: R Q D 8 H 9 L O P T E F M 6 I A 7 J 5 4 B U 2 G.

- Find the 7th element from the left:

Start counting from R:

1. R

2. Q

3. D

4. 8

5. H

6. 9

7. L

- Find the 9th element from the right:

The arrangement has 24 elements. So, counting from right,

1. G

2. 2

3. U

4. B

5. 4

6. 5

7. J

8. 7

9. A

- So, the two required elements are L and A.

- Now, list how many alphabets (based on the English dictionary order) come between L and A:

- Alphabetically, from A to L: B, C, D, E, F, G, H, I, J, K (10 alphabets).

- So, count is 10.
