In a sports club with 27 members, 17 play badminton and 19 play tennis and 2 do not play either. How many members play both badminton and tennis? Choose the correct choice from the following answers:
A) 7  B) 8  C) 9  D) 10  E) 11
Let x play both badminton and tennis so 17-x play only badminton and 19-x play only tennis. 2 play none and there are total 30 students. hence,   (17-x)+(19-x)+x+2=27   38-2x+x=27   38-x=27   x=11   So 8 members play both badminton and tennis.   11
<result>E</result>
