Problema Solution

Two factory plants are making TV panels. Yesterday, Plant A produced 4 times as many panels as Plant B. Three percent of the panels from Plant A and 5% of the panels from Plant B were defective. How many panels did Plant B produce, if the two plants together produced 1700 defective panels?

Answer provided by our tutors

Let Plant B produced x panels, Then

A prodeced 4x panels.

Total defective panels is 1700 i.e.

0.03*4x + 0.05x = 1700

orx = 1700/0.17

so, x= 10000
