Five letters N, L, E, B, O are used to form a meaningful word. Given the conditions:

- O is second to the left of E.
- B is an immediate neighbor of O.
- E is immediately to the left of L.
- N is placed at one of the corners.

Find the third letter from the right end of the word formed. If more than one word can be formed, mark X as your answer.

Question

Five letters N, L, E, B, O are used to form a meaningful word. Given the conditions:

- O is second to the left of E.
- B is an immediate neighbor of O.
- E is immediately to the left of L.
- N is placed at one of the corners.

Find the third letter from the right end of the word formed. If more than one word can be formed, mark X as your answer.

Accepted Answer

**Solution:**

1. The letters are N, L, E, B, O.

2. Conditions given:
   - O is second to the left of E.
   - B is an immediate neighbor of O.
   - E is immediately to the left of L.
   - N is placed at one of the corners.

3. Let's analyze step-by-step:

- Since O is second to the left of E, the relative positions are: O _ E.

- E is immediately to the left of L, so E L are adjacent with E before L.

- B is an immediate neighbor of O, so B is either immediately left or right of O.

- N is at one of the corners (either first or last position).

4. Try to place letters:

- Place N at the first position (corner): N _ _ _ _

- O must be second to the left of E, so if O is at position 2, E is at position 4.

- E is immediately left of L, so L is at position 5.

- B is neighbor of O, so B must be at position 3 (next to O at 2).

So the arrangement is:
   N O B E L

5. Check if this forms a meaningful word: "NOBEL" is a valid English word.

6. Third letter from the right end:
   - From right: L (1st), E (2nd), B (3rd)

So the third letter from the right is B.

7. But the options mark O as correct. Let's re-check the neighbor condition:

- B is neighbor of O (true, B is right next to O).

- O is second to the left of E (positions 2 and 4, true).

- E is immediately left of L (positions 4 and 5, true).

- N is at corner (position 1, true).

8. Third letter from right is B, but option B is false, option O is true.

This indicates a mistake in the initial answer key.

9. Let's try placing N at the last position:

- Positions: _ _ _ _ N

- O second to left of E means if E is at position 4, O is at position 2.

- E immediately left of L means L is at position 5, but 5 is N here, so no.

- Try E at position 3, O at position 1.

- B neighbor of O means B at position 2.

- E immediately left of L means L at position 4.

So arrangement: O B E L N

10. Check if meaningful word: "OBELN" is not a word.

11. So only valid word is "NOBEL".

12. Third letter from right in "NOBEL" is B.
