1. Compute the increase in the number of correct answers:
   $$
   30 - 25 = 5
   $$

2. Use the percent increase formula:
   $$
   \text{Percent Increase} = \frac{\text{Increase}}{\text{Original Value}} \times 100\%
   $$
   Substitute the values:
   $$
   \frac{5}{25} \times 100\%
   $$

3. Calculate the fraction:
   $$
   \frac{5}{25} = 0.2
   $$

4. Convert to a percentage:
   $$
   0.2 \times 100\% = 20\%
   $$

The percent increase is $$20\%$$.
The percent increase is 20%.
