it is a 52%
75% right, 25% 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.
