A. 27%
B. 21%
C. 19%
D. 18%
E. 16%
Since we are asked to find a PERCENT (and not an actual value), let's choose a nice value for the total number of parents.
Let
100 = the total number of parents
Number of mothers = 40% of
100 =
40
Number of fathers = 60% of
100=
60
Number of mothers WITH full-time job = 3/4 of
40 =
30
Number of fathers WITH full-time job = 9/10 of
60 =
54
Total number of parents with full-time job =
30 +
54 =
84
Thus parents without full time job = 100 -
84 = 16
So, 16 of the 100 parents do not have full-time jobs.
In other words, 16% of them do not have full-time jobs
Answer: E
