Is there a possible way to figure out what I got on my final exam?

Ok my average was 80% but my final average is 78% which is


decent I guess. Anyways my final exam had 90 questions and was worth 20% of my final mark, is there a way possible to figure out how I did on my exam?Is there a possible way to figure out what I got on my final exam?
80%(80) + 20%(x) = 78


20%(x) = 78 - 64


20%(x) = 14


x = 70


that's 70% of the 90 questions, so your score was 63 out of 90.Is there a possible way to figure out what I got on my final exam?
Yes, there is.





Here goes...





You had 80% going into the exam and this was worth 80% of your final mark.





We can say that you had 80% of the 80 marks already given or





64/80 for your course work.





As a final mark, you got 78...so you must have got (78-64) = 14 marks from writing the exam.





So on the exam, you got 14 out of a possible 20, or 70%





That means out of the 90 questions, you got 70% of them right (63).





So the bottom line...





You got 63 out of 90 or 70% on your final exam.





Now, don't worry about it and either go and celebrate or move on to thinking about the next exam you have!
yes.





80 X .8 + n X .2=78





64 + .2n= 78





.2n=14





n= 14/.2





n= 70
Sure--





.20 x (grade) + .8 * 80 = 78





Grade = 70
you know you could just find your teacher and ask for your final back.
