Answer: 6 students
What we know:
Students: 24
Students who play checkers: 
Students who also play sudoku:
of the 
24 ÷ 3 = 8, so 8 × 2 = 16 (students who play checkers)
× 2 = 
So the answer is,
6 students play both checkers and sudoku
Answer with Step-by-step explanation:
We are given that
F=<0,-8>=0i-8j=-8j

The component of force is divided into two direction
1.Along the plane
2.Perpendicular to the plane
1.The vector parallel to the plane will be=
By using 
Force along the plane will be=
Force along the plane will be =
N
By using 
Therefore, force along the plane=
2.The vector perpendicular to the plane=
The force perpendicular to the plane=
The force perpendicular to the plane=
N
Therefore, 
Sum of two component of force=
Sum of two component of force=
Hence,sum of two component of forces=Total force.
