A total of Y tourists were transported by bus to a certain museum. If there were Z tourists on each bus, which of the following expresses the number of buses used?
Options
A) YZ  B) Y/Z  C) Z/Y  D) Y-Z  E) Z^2
IMHO (Y/Z)Y/Z as well !   Number of buses used = Total number of tourists / Number of tourists per bus =&gt; Y/Z   PS : In case of any doubt , plug in some numbers   Total number of tourists transported by bus = 500   Number of tourists per bus = 10   No of buses required = 500/10
<result>B</result>
