of the 50 hotels in the hilltop hotels chain,5 have indoor swimming pools and 15 have outdoor swimming pools.What percent of all hilltop hotels have either an indoor or an outdoor swimming pool?
再次支持楼主!加油!
翻译:山顶酒店产业链的50家酒店中,有5家有室内游泳池,有15家有室内游泳池.请问拥有室内或者室外游泳池之一的酒店占百分之多少?
首先,题目条件给得不算严格(楼主可以再仔细看一下题目有没有其他条件或者说法),因为没有说明是否有酒店同时拥有室内游泳池和室外游泳池,有多少家,所以解题时可以假设没有这样的酒店存在.这样tristanli的解答就是正确的(5+15)/50=40%
