Answer:

She get 747 questions correct and 83 questions incorrect.

Explanation:

Given that she attempted a total of 830 questions in the quiz.

Percentage of the incorrect question = 10%

So, the number of incorrect question = 10% of 830


=\frac {10}{100}* 830= 83

Now, 10% of the questions are incorrect, so the percentage of correct questions = 100-10= 90%

Therefore, the number of incorrect question = 90% of 830


=(90)/(100)* 830=747

Hence, she get 747 questions correct and 83 questions incorrect.
