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

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
