In a survey of parents, exactly 3/4 of the mothers and 9/10 of the fathers held full-time jobs. If 40 percent of the parents surveyed were women, what percent of the parents did not hold full-time jobs? Choose the correct choice from the following choices:
A) 27%  B) 21%  C) 19%  D) 18%  E) 16%
Let the total number of parents = 100   Number of women = 40   Number of men = 60   Number of mothers who held full time jobs = 3/4*40= 
<gadget id="calculator">3/4*40</gadget>
<output>30</output>
30   Number of fathers who held full time jobs= 9/10*60= 
<gadget id="calculator">9/10*60</gadget>
<output>54</output>
54   Total number of parents who held full time jobs= 84   Total number of parents who did not hold jobs = 100 - 84= 
<gadget id="calculator">100 - 84</gadget>
<output>16</output>
16   Alternatively ,   Percentage of women= 40%   Percentage of women who did not hold full time jobs = (1-3/4)*100= 
<gadget id="calculator">(1-3/4)*100</gadget>
<output>25</output>
25% of all mothers did not have full time jobs   25% of 40 % --&gt; 10 % of the total parents   Percentage of men= 60%   Percentage of men who held full time jobs = (1-9/10)*100= 
<gadget id="calculator">(1-9/10)*100</gadget>
<output>10</output>
10% of all fathers did not have full time jobs   10 % of 60% --&gt; 6 % of the total parents   Therefore , percentage of parents who did not hold full time jobs= 10+6= 
<gadget id="calculator">10+6</gadget>
<output>16</output>
16%   Answer 16% - 16%
<result>E</result>
