Ten students in a computer skills company can touch-type and the other 15 can use a particular word processing program. If 13 of the students can neither use the program nor touch-type, then how many students are in the class?	Choose the correct choice
A) 46 B) 42 C) 38 D) 34 E) 19
the neither = 13 , the minimum number of students in any or both = 15 , thus 19 is out   the maximum number of students (given 13 is in neither ) in any or both could reach = 25 thus 42 and 46 are out   now the answer is b or c both could be the answer   if the intersection between the 2 groups = 0 thus total = 13+15+10=

<output>38</output>
38   if the intersection between the 2 groups= 4 thus total = 15+6+13 or  11+10+13=

<output>34</output>
