- Let's first analyze the given conditions:

- 80% of A is 13 more than 90% of B, expressed as: 0.8A = 0.9B + 13.

- The ratio of 40% of A to 60% of B is 10:9, expressed as: (0.4A)/(0.6B) = 10/9.

- Simplifying the second equation:

- Multiply both sides by 0.6B to get: 0.4A = 0.6B * (10/9).

- This results in: 0.4A = (2/3)B.

- From these equations, we can find A and B:

- Substitute B from the second equation into the first: 0.8A = 0.9((3/2)(0.4A)) + 13.

- Solve this to get the relation between A and B.

- Finally, solve for A-B and find the value.

- After calculating, the correct option is: Option 1: 50
