To find the percentage of incorrect answers, divide the number of wrong answers by the total number of questions and then multiply by 100. So, ( \frac{13}{40} \times 100 = 32.5% ). Therefore, 32.5% of the answers are wrong.
To find the percentage of wrong answers, divide the number of wrong answers (10) by the total number of questions (40), then multiply by 100. So, (10/40) × 100 = 25%. Therefore, 25% of the answers are wrong.
40-26=14 questions answered correctly. 14/40=.35 Therefore the percentage of the test would be 35%
