    [SOLVED] Percents

    I took a test that had 80 questions. Out of the 80 questions, they said I had 69% score. How many questions did I miss?

    69% of 80 is 0.69*80=55.2.

    So you had correct answers to the equivalent of 55 and 1/5 questions.

    test results

    actually its:

    .69 * 80 = 55.2

    but you probably got 55 q's right and they calculated the percentage as

    55 / 80 = .6875 which was rounded to 69%

    so you missed 80 - 55 = 25 questions

    out of 100=69
    out of 80 = (80*69)/100
    = 55.2

    no of attempted questions =55.2

    questions not attempted 80-55.2
