A bottle company produces 100 glass bottles per day. One-fifth of the bottles produced are defective and one-quarter of all bottles produced are rejected by quality control technician. If one-tenth of the nondefective bottles are rejected by mistake, and if all the bottles not rejected are sold, then what percent of the bottles sold by the company are defective?
Choose one.
A) 16%	B) 8%	C) 4%	D) 2%	E) 1%
We have 20% defective and 80% non-defective; we have 25% rejected and 75% not rejected. We also know that 1/10 of the non-defective ones (8%) are rejected, so 72% sold. This means that we have 3% sold that are defective and 17% rejected that are defective. Overall, we have 3%/75% or 1 of every 25 that are sold (not rejected) and defective. 4%orrect Answer is 4%
