Four questions.

20
19/20 as a percentage = 100*19/20 = 95%
If you got four out of twenty questions wrong, you answered 16 out of 20 questions correctly. To find the percentage of questions answered correctly, you would divide 16 by 20 and then multiply by 100. This means you answered 80% of the questions correctly.
(18 ÷ 20) × 100 = 90 Therefore: 90%
Answer 7 correctly.
you explain how to solve this question? If there is an equation that I can use will be appreciated. 70% of students answered question A correctly, 55% of students answered question B correctly, 20% of students answered neither question correctly. What is the percentage of students answered both question A and B correctly?

20%
90% of 20 questions = 90*20/100 questions = 1800/100 = 18 questions.

Divide the number of correct answers by the total number of answers. If you answered 17 out of 20 questions correctly, 17/20 = 0.85 or 85%
You can get 20 questions wrong.
