of the 50 hotels in a hotel chain, 5 have indoor pools and 15 have outdoor pools. what percentage have either an indoor or outdoor swimming pool?

Question

this question is from the princeton review cracking the SSAT and ISEE

Answer 1

Hi Ella,

 

So to re-phrase the information in this question, we are told that a hotel chain (such as Hilton Hotels) is made up of a total of 50 hotels. Of the 50 hotels, 5 have indoor pools and 15 have outdoor pools (and I assume the remaining number of hotels have no indoor or outdoor pools). The question is asking, as a percentage, how many of the total 50 hotels contain indoor or outdoor pools. 

 

So that's;

 

[(5+15)/50]x100

=40%

 

The answer is: 40% of the hotels in this hotel chain have indoor or outdoor pools

 

Hope this helps,
