Let the number of graduate employees be \( g \) and the number of undergraduate employees be \( u \). According to the problem, we have the initial ratio of graduates to undergraduates as:
\[
\frac{g}{u} = \frac{1}{4}
\]
From this ratio, we can express \( u \) in terms of \( g \):
\[
u = 4g
\]
Next, we are informed that 10 more persons joined the company, and some of the employees acquired graduation degrees, which resulted in a reduction of
