C Correct answer
Explanation

We have A/C = 3/5. To find C, we need the value of A or the difference between A and C. Statement II gives A-C = 10 (or C-A = 10), which allows solving for C. Statement I and III together give A = B-3 and C = B+7, so C-A = 10, which also allows solving for C. Thus, II alone or I and III together are sufficient.

D Correct answer
Explanation

Statement I: A/K = 3/5, K+G = 28. Statement II: K = 2A - 4. Statement III: K = 2G + 4. With any two statements, we can solve for A, K, and G. For example, I and II allow solving for A and K, then G. I and III allow solving for K and G, then A.
