Seven individuals S, E, V, B, A, D, and U are seated in a row facing north. Each has a unique work experience of 15 years, 7 years, 2 years, 23 years, 19 years, 6 years, and 12 years respectively, but not necessarily in the order given. The following conditions apply:

- Persons with vowel names have even years of experience and none of them sit at either end or exactly in the middle of the row.
- There are three persons seated between S and the person with 23 years of experience.
- Exactly one person sits between S and A.
- The number of persons to the right of A equals the number of persons to the left of the person whose experience is 2.5 times that of A.
- B neither has the highest experience nor sits next to S.
- The person with the least experience sits second to the left of D.
- U does not have the least experience.
- Both neighbors of B have more experience than B.

Which of the following is the correct combination of person and their experience?

Question

Seven individuals S, E, V, B, A, D, and U are seated in a row facing north. Each has a unique work experience of 15 years, 7 years, 2 years, 23 years, 19 years, 6 years, and 12 years respectively, but not necessarily in the order given. The following conditions apply:

- Persons with vowel names have even years of experience and none of them sit at either end or exactly in the middle of the row.
- There are three persons seated between S and the person with 23 years of experience.
- Exactly one person sits between S and A.
- The number of persons to the right of A equals the number of persons to the left of the person whose experience is 2.5 times that of A.
- B neither has the highest experience nor sits next to S.
- The person with the least experience sits second to the left of D.
- U does not have the least experience.
- Both neighbors of B have more experience than B.

Which of the following is the correct combination of person and their experience?

Accepted Answer

**Solution:**

1. Since persons with vowel names (E, A, U) have even years of experience and none of them sit at the ends or exactly in the middle (4th position), they must occupy positions 2, 3, 5, or 6.

2. The row has 7 seats facing north, positions numbered 1 to 7 from left to right.

3. Three persons sit between S and the one with 23 years experience, so their positions differ by 4.

4. One person sits between S and A, so their positions differ by 2.

5. The number of persons to the right of A equals the number of persons to the left of the person whose experience is 2.5 times that of A.

6. B neither has the highest experience (which is 23 years) nor sits adjacent to S.

7. The person with the least experience (2 years) sits second to the left of D.

8. U does not have the least experience.

9. Neighbors of B have more experience than B.

By carefully placing the persons according to these conditions and matching experience:

- Assign vowel persons E, A, U to positions 3, 5, and 6 (none at ends or middle).
- Let A have 2 years experience (lowest), so the person with experience 2.5 times A's is 5 years, but since 5 years is not in the list, check other possibilities.
- After testing combinations, U is found to have 12 years experience, satisfying all conditions.

**Answer:** U - 12 years
