If $50 \%$ of $P$ equals $20 \%$ of $Q$, then $P$, as a percent of $Q$, is
(A) $60 \%$
(B) $250 \%$
(C) $40 \%$
(D) $20 \%$
(E) $30 \%$

Part B: Each correct answer is worth 6.
Since $50 \%$ of $P$ equals $20 \%$ of $Q$, then $\frac{1}{2} P=\frac{1}{5} Q$ or $P=\frac{2}{5} Q$.

Therefore, $P$ is $40 \%$ of $Q$.

ANSWER: (C)
