There are some balls in the box 25% of the balls are green 45% are red the rest is blue there are 30 more red balls that blue balls how many green balls are in the box

Let the total number of balls in the box be denoted by \( N \). We are given the following information:

- 25% of the balls are green, so the number of green balls is \( 0.25N \).
- 45% of the balls are red, so the number of red balls is \( 0.45N \).
- The rest are blue, so \( 1 - 0.25 - 0.45 = 0.30 \), meaning 30% of the balls are blue, so the number of blue balls is \( 0.30N \).
- There are 30 more red balls than blue balls, so:
  \[
  0.45N = 0.30N + 30
  \]

### Step 1: Solve for \( N \)
Subtract \( 0.30N \) from both sides:
\[
0.45N - 0.30N = 30
\]
\[
0.15N = 30
\]
Now, divide by 0.15:
\[
N = \frac{30}{0.15} = 200
\]

### Step 2: Calculate the number of green balls
The number of green balls is 25% of the total number of balls:
\[
0.25N = 0.25 \times 200 = 50
\]

### Final Answer:
There are **50 green balls** in the box.
