Step 1:Let's solve this step by step:
Step 2:: Identify the total number of questions
- Total questions = 25
Step 3:: Calculate the number of questions needed to score 80%
- Percentage of correct questions = $$\frac{correct questions}{total questions} \times 100\% = 80\%
- To score 80%, you must get at least 80% of the questions correct
Step 4:: Calculate the number of correct questions required
- Correct questions = $$25 \times 0.80 = 20$$ questions
Step 5:: Calculate the number of questions you can get wrong
- $$25 - 20 = 5$$ questions
- Questions you can get wrong = Total questions - Correct questions
Step 6:: Verify the calculation
- $$\frac{20}{25} \times 100\% = 80\%
- If you get 20 questions correct and 5 questions wrong out of 25 total
Final Answer
You can get 5 questions wrong and still score 80% on a 25 -question test.
