$\text{Hello!}$

$\large\boxed{1.25\%}$

$\text{Use the simple interest formula I = P * r * t where:}\\\\\text{I = amount of interest}\\\text{P = principle (initial amount)}\\\text{r = interest rate}\\\text{t = time period}\\\\\text{Substitute the known values from the problem:}\\\\1250 = 25000 * r * 4\\\\1250 = 100000r\\\\r = 0.0125\\\\\text{Convert to a percentage:}\\\\0.0125 * 100 = 1.25\%$
