Solution: If the annual interest rate in the first year is X, the interest in the first year is 50000x yuan; According to the meaning of the question, you can list the equations.

(50000+50000 x- 125)(x-0.27%)= 50000 x- 1 15.2

To solve this equation, x≈0.0 1729 = 1.729%.

A: The annual interest rate for the first year is 1.729%.
