4 wrong out of 20 questions what is your grade?

To determine your grade based on 20 questions with 4 wrong answers, you first need to calculate the total number of questions answered correctly. Subtract the number of wrong answers (4) from the total questions (20) to get the correct answers (20 - 4 = 16). Then, divide the number of correct answers (16) by the total questions (20) and multiply by 100 to get the percentage. So, your grade would be 80%.
