Are you sure you wrote down the problem correctly?

Let the number of apples bought be $3n,\ 0 \leq n \leq 5$.

Then the number of oranges bought is $5(5-n)$.

So there are several different correct answers.

If n= 0, he bought no apples and 25 oranges.

If n= 1, he bought three apples and 20 oranges, etc.
