Question

Two factory plants are making TV panels. Yesterday, Plant A produced 9000 panels. Ten percent of the panels from Plant A and 3% of the panels from Plant B were defective. How many panels did Plant B produce, if the overall percentage of defective panels from the two plants was 6%?

Answer 1

Answer:

Panels produced by Plant B = 12000

Step-by-step explanation:

Let the number of panels produced by plant B be 'x'

Now, according to the given information;

⇒ $9000(\frac{10}{100} ) + x(\frac{3}{100} ) = (9000 + x)(\frac{6}{100} )$

⇒ $90000 + 3x = 54000 + 6x$

⇒ x = 12000
