Given total number of student in the class = 30
number of students who like football = 6
number of students who like cricket = 12
so no. of students who like tennis = total no. of students in the class - (sum students who like football and cricket = 30 - (6 12) = 12
a) no. of students who like football : number of students who like tennis = 6 : 12 = 6/12 = 1 : 2
b) no. of students who like cricket : total number of students = 12 : 30 = 12 / 30 = 2 : 5
