Given the following question:


\begin{gathered} 30+70+50+50=200 \\ 200\text{ people in total} \\ \text{30 of the 200 people want tacos and are a fan of team A} \\ (30)/(200)/10=(3)/(20) \\ =(3)/(20) \\ \text{ Out of every 20 people 3 will want tacos while being fans of team A} \end{gathered}

Your answer is option D.
