求高手详细讲解一下这道data sufficiency
Of the 66 people in a certain auditorium, at most 6 people have their birthdays in any one given month. Does at least one person in the auditorium have a birthday in January?
(1) More of the people in the auditorium have their birthday in February than in March.
(2) Five of the people in the auditorium have their birthday in March.
为什么答案解析给出的是假设66个人平均的分在11个月中,为什么要均衡的分,就是这个地方不是很清楚 |
