Its simple...use venn diagram...
student playing all 3=20
student playing volley and cricket only = 0
student playing volley and hockey = 30...means 20 who plays all three and 10 only these 2 sports.
no of only volley players left =70-20-10 =40

last , students playing hockey and cricket = 30..
same goes here ...
therefore no of stu. playing only hockey and cricket =10
no. of only hockey players left= 20- 10(stu. with ho key and cricket only)-10(student playing hockey and volley only)
so, 60-20-10-10 = 20

Ratio of volley to hockey =40:20
= 2:1
