- The sum of the five numbers, A, B, C, D, and E, is 37.5.

- The average of A and B is 6, which means (A + B) / 2 = 6. Therefore, A + B = 12.

- The average of D and E is 9, which means (D + E) / 2 = 9. Therefore, D + E = 18.

- To find C, we subtract A + B and D + E from the total sum: C = 37.5 - 12 - 18 = 7.5.

- The average of A, B, and C is (A + B + C) / 3.

- Substitute the values: (12 + 7.5) / 3 = 19.5 / 3 = 6.5.

- Option: 3 - 6.5 is correct.
