22balls
Step-by-step explanation:
Using the method of equality,
Since 9 defective balls are produced in a lot of 275, and 17 defective balls are produced in a lot of 450, and let 'x' be number of defective balls produced out of lot of 675.
So then have;
9 balls = 275lots ...eqn 1
17 balls = 450 lots...eqn 2
x balls = 675 lots...eqn 3
To calculate x, we cross multiply any two out of the three equations. Using eqn 2 and 3,
17 balls = 450 lots...eqn 2
x balls = 675 lots...eqn 3
450x = 17×675
x = 17×675/450
x= 22balls
