Question

Let the students who likes table tennis be 12, the ones who like lawn tennis 10, those who like only table tennis are 6, then number of students who likes only lawn tennis are, assuming there are total of 16 students.

Answer 1

T=table tennis=12

L=lawn tennis=10

T&L=both=6

total=16

only T=12-6=6

only L=10-6=4

only lawn tennis =4
