1987 AJHSME Problems/Problem 23

From AoPSWiki

Problem

Assume the adjoining chart shows the 1980 U.S. population, in millions, for each region by ethnic group. To the nearest percent, what percent of the U.S. Black population lived in the South?

\begin{tabular}[t]{c|cccc} & NE & MW & South & West \\ \hlineWhite & 42 & 52 & 57 & 35 \\Blac...

\text{(A)}\ 20\% \qquad \text{(B)}\ 25\% \qquad \text{(C)}\ 40\% \qquad \text{(D)}\ 56\% \qquad \text{(E)}\ 80\%

Solution

There are 5+5+15+2=27 million Blacks living in the U.S. Out of these, 15 of them live in the South, so the percentage is \frac{15}{27}\approx 56\%.

\boxed{\text{D}}
