With 3 wrongs out of 8 questions your average is (3/8)x100 = 37.5% wrong and 62.5 correct.
toget 80% you need .8 x 15 = 12 questions right. That means you can 15-12 = 3 questions wrong
8 wrong i.e. 32 right 10% of 40 is 4 80% = 8 x 4 = 32 40 - 32 = 8

Each question is worth 2.5 percent. You can get 8 wrong.
The 2 questions that were wrong equals 25% of the score because each question is 12.5%. So if 2 questions out of 8 were wrong the score would come out to 75%. The equation to get the answer is (100 / 8 = 12.5) So (12.5 x 2 = 25) Now that you know that the questions that were answered wrong equals 25% just do (100% - 25% = 75%) So then 75% is your answer.

60% right, 40% wrong.
To achieve 80 percent on a 40-question test, you need to answer at least 32 questions correctly (80% of 40 is 32). This means you can only get 8 questions wrong (40 - 32 = 8). Therefore, to score 80 percent, you can afford to miss a maximum of 8 questions.
