Explanation: If we say that there are n people in the town, 0.64n are employed, and 0.48n are men who are employed. That means that the difference--0.16n--represents women who are employed. The question asks for the percent of employed people (0.64n) that are female (0.16n):

((0.16n)/(0.64n)) = ((16n)/(64n)) = (16/64) = (1/4), choice (B).
