Answer: 1,000 products
Explanation:
If 20 out of 800 products are found to be defective, the percentage of defective products would be:
= 20 / 800
= 2.5%
At this same rate of 2.5%, if there are 40,000 products instead of 800, the number of defective products would be:
= 2.5% * 40,000
= 1,000 products
