In year X, 8.7 percent of the men in
the labor force were unemployed in
June compared with 8.4 percent is
May. If the number of men in the
labor force was the same for both
months, how many men were
unemployed in June of that year?
(1) In May of year X, the number of
unemployed men in the labor
force was 3.36 million.
(2) In year X, 120,000 more men in
the labor force were unemployed
in June than in May.

oa is D

Solution:

Question Stem Analysis:

We need to determine the number of men who were unemployed in June of year X. We can let m = the total number of men in the labor force in both June and May, then the number of men who were unemployed in June is 0.087m (and the number of men who were unemployed in May is 0.084m). We see that if we can determine the value of m, then we can determine the value of 0.087m, i.e., the number of men who were unemployed in June.

Statement One Alone:

We can create the equation 0.084m = 3,360,000, and thus we can determine the value of m and hence the value of 0.087m. Statement one alone is sufficient.

Statement Two Alone:

We can create the equation 0.087m - 0.084m = 120,000 and thus we can determine the value of m and hence the value of 0.087m. Statement two alone is sufficient.

Answer: D
