answer: 3 to 4

there are 3 times as many people aged 21 or under as there are people over 21

难道是说21岁以下的人是21岁以上的3倍？

yes, you don't need to care about the reality of the assumption. And by the way, May I know how do you guys solve the #62 and #63. And could you tell me how to handle the problems of MEDIAN? Such as #65, #68. Many thanks!

请楼主先看语文语法.如果一个事物由A,B两部分组成,A是B的3倍,A+B=4B, AA+B)=3:4
