Problema Solution
two factory plants are making tv panels. yesterday plant A produced 5000 less panels than plant B. 5% of the panels from plant A and 4% of the panels form plant B were defective. how many panels did plant B produce if the plants together produced 830 defective panels?
Answer provided by our tutors
let
a = the number of panels produced in plant A
a + 5000 = the number of panels produced in plant B
5% of the panels from plant A and 4% of the panels form plant B were defective and the plants together produced 830 defective panels
0.05a + 0.04(a + 5000) = 830
by solving we find
a = 7000 panels

a + 5000 = 7000 + 5000 = 12,000 panels
plant B produced 12,000 panels.
