A(Red) : A(Blue)

5 units : 9 units (Before)

5 units : 6 units (After)

11 units = 385

1 unit = 35

3 units = 105 (Transfer to Box B)

**Answer for (a): 5:6**

B(Red) : B(Blue)

3 : 1

21 parts : 7 parts (Red is constant)

7 : 4

21 parts : 12 parts (Red is constant)

5 parts = 105

1 part = 21

33 parts = 693

**Answer for (b) = 693**
