Given information:
- Ratio of earnings of A and B is 3:5
- After the changes, the new ratio becomes 6:8
Let's assume the initial earnings of A and B to be 3x and 5x respectively.
Calculating the new earnings after the changes:
- A's earnings increase by 25%, so the new earnings of A = 3x + 0.25(3x) = 3.75x
- B's earnings decrease by 30%, so the new earnings of B = 5x - 0.30(5x) = 3.5x
Given that the new ratio of earnings is 6:8:
- The new ratio of A's earnings to B's earnings is 6:8
- Therefore, 3.75x/3.5x = 6/8
- Solving this equation, we get x = 2
Calculating A's earnings:
- A's initial earnings = 3x = 3(2) = 6
Therefore, A's earnings are 6 units.
