谁能帮忙翻译一道英文数学题？（百度翻译的不要，谢谢~）The scores reported for a certain multiple-choice test were derived by subtracting 1/3 of the number of wrong answers from the number of right answers. On a 40-question test, if none of the question was omitted and the score reported was 20, how many wrong answers were there?

Answer 1

计算考试成绩的方式如下：（答对的题）- （答错的题除三）。
考试40道题，如果所有题都回答了，最后的成绩是20，请问错了多少题？

如果需要的话，答错 15， 答对 25.
25-（15/3）= 25-5=20

Answer 2

一定的多项选择题测试的分数报告导出减1/3的数量错误的答案正确答案的数量。在40题测试,如果没有问题是省略了分数报道20岁的时候,有多少错误的答案吗?
