求助~~~有一道prep的题目DS 题目，个人觉得答案有些牵强，请大牛指点迷津啊~~~

题目如下：
On a certain sight-seeing tour, the ratio of the number ofwomen to the number of children was 5 to 2. What was the number of men on thesight-seeing tour?

(1)   On the sight-seeing tour, the ratio of thenumber of children to the number of wen was 5 to 11
(2)   The number of women on the sight-seeing tour wasless than 30
他答案选择了C 也就是说条件1+条件2 放在一起可以推算出有多少个men。但是他条件二中明显是说此次旅行中的女性是少于30的呢？
是不是因为人一定是整数所以，答案就是女性有25个，小孩儿10个，男性22个呢？
谢谢啊~~~
