5명의 친구 휠릭, 도리, 타인, 리가, 총알(생각나는 대로 썼습니다)이 이번에 치른 수학 시험에 대하여 대화를 나누고 있다. 이번 수학 시험에서 성적이 오른 사람들의 이전 수학 시험 성적의 평균을 구하여라.
타인 : 이번에 치른 시험에서 우리 5명의 시험 성적의 평균이 1.6점 올랐어.
리가 : 맞아. 그리고 성적이 떨어진 사람은 없어.
휠릭 : 2명이 성적이 올랐어.
도리 : 성적이 오른 사람들의 이번 시험 성적의 평균은 86점이야.
총알 : 규카츠 먹고 싶다
(타인, 리가, 휠릭, 도리님께서는 문제에 자신의 이름이 올라가는 것이 싫으시면 댓글을 남겨주세요)
