Let's denote Gia's current age as \( g \).
In 4 years, Darius will be \( 38 + 4 = 42 \) years old, and Gia will be \( g + 4 \) years old.
According to the problem, in 4 years, Darius will be 3 times as old as Gia:
\[
42 = 3(g + 4)
\]
Now, we can solve for \( g \):
\[
42 = 3g + 12
\]
Subtract 12 from both sides:
\[
42 - 12 = 3g
\]
\[
30 = 3g
\]
Now, divide both sides by 3:
\[
g = 10
\]
So, Gia is currently **10 years old**.
