Problema Solution
Two factory plants are making TV panels. Yesterday, Plant A produced 6000 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 5% ?
Answer provided by our tutors
(6000 + b) x 0.05 = (0.10 x 6000) + (0.03 x b)
or, b = 0.02b =600 - 300 = 300
or, b = 30000/2 = 15000
