Answers
Given:
Number of children=24
Children who play cricket=16
Children who play only cricket=12
To find:
The number of children who play only hockey
Solution:
The number of only hockey-playing children is 8.
Total students=number of cricket-playing students+number of hockey-playing students-number of cricket and hockey playing students
The number of cricket and hockey playing students=Number of cricket playing students - number of only cricket playing students
=16-12
=4
Using the values,
24=16+ number of hockey-playing students - 4
24=12+number of hockey-playing students
24-12=number of hockey-playing students
12=number of hockey-playing students
Now, the number of only hockey-playing children=number of hockey-playing children - number of children who play both
The number of only hockey-playing children=12-4=8
Thus, the number of only hockey-playing children is 8.
