One hundred people attended a party. Fifty percent of the attendees are women, thirty-five percent of them are men, and the rest are children. How many children attended the party?
Out of 100 attendees, 100 x 50/100 = 
<gadget id="calculator">100*50/100</gadget>
<output>50</output>
50 are women.
While 100 x 35/100 = 
<gadget id="calculator">100*35/100</gadget>
<output>35</output>
35 are men.
