on a certain sight-seeing tour,the ratio of the number of the women to the number of the chidern was 5 to 2,what was the number of men on the sight-seeing tour?

1) on the sight-seeing tour, the ratio of the number of chidren to the number of men was 5 to 11

2) the number of women on the sight-seeing tour was less than 30

答案是 C

我选的E

由LESS THAN 30怎么能得出确定的 the number of men

求解释

 1. 根据ratio, women:children:men = 25:10:22

1+2. 因为women小于30人，人为整数，则women只能为25,men为22
