Let's break it down:

- The ratio of marbles in A : B : C is 3 : 5 : 7, and the total is 75.

- Let the number of shares be 3x, 5x, 7x.

- 3x + 5x + 7x = 75 ? 15x = 75 ? x = 5.

- So, A = 15, B = 25, C = 35.

- After moving marbles:

- 3 marbles from B to A: A = 18, B = 22.

- 5 marbles from C to B: C = 30, B = 22 + 5 = 27.

- New numbers: A = 18, B = 27, C = 30.

- New ratio: 18:27:30 ? dividing by 3: 6:9:10.

- Option 4: 6:9:10 is correct.
