Strategic Advice: Whenever information is presented in a table, be sure to read the column and row headers carefully and only use the information that applies to the question.
Getting to the Answer: Before you can apply percentages from the table, you need to determine how many men and how many women there were in the workforce in the district. The number of men was 53.5% of 12,800, or 0.535 × 12,800 = 6,848, and the number of women was 12,800 - 6,848 = 5,952. Now, use the information from the table for April:
Men: 5.5% of 6,848 = 0.055 × 6,848 = 376.64, or about 377 unemployed men
Women: 5.4% of 5,952 = 0.054 × 5,952 = 321.408, or about 321 unemployed women
This means there were 377 - 321 = 56 more unemployed men than women in the district in April. Choice (B) is correct.
