Providing that the other 5 questions are correct then it is a 62.5% score
25 - 8 = 17 Providing each of the questions carry the same mark.
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.
If you score 7 out of 8 you have a percentage score of 87.5%.
a score is 20 years so 8 score is 8 x 20 = 160 years
8/12 which is 67%
Eight score is 8 x 20 which is 160
