Total number of students = 30 

Number of students like football = 6 

Number of students like cricket = 12 

Thus number of students like tennis = 30 – 6 – 12 = 12 

(a) The ratio of students like football that of tennis = 6/12 =1/2 = 1 : 2 

(b) The ratio of students like cricket to that of total students = 12/30 = 2/5 = 2 : 5
