Solution


The number of manufacturing industry workers who were unemployed for 5 to 10 weeks is 20% of 10 million, or 2 million; and the number of service industry workers who were unemployed for 5 to 10 weeks is
16% of 8 million, or 1.28 million. Thus, the ratio of the two numbers is \(\frac{2}{1.28.}=1.5\) circa

Looking at the answer choices only C with its fraction \(\frac{3}{2}=1.5\) is closer.

The answer is \(C\)
