Question 1199257
.


        If you do not know proportions (in case if you did not 
        study them yet),  you can use this reasoning.



72  good guys comprise  6  groups of  12  good guys,  each.


Hence,  there are  6 groups of  5  bad guys on the scene,  each.


6 * 5 = 30,  &nbsp;&nbsp;so the <U>ANSWER</U> &nbsp;&nbsp;is:  &nbsp;&nbsp;&nbsp;&nbsp;there were &nbsp;30 &nbsp;bad guys.
