Question

At a certain factory, 10 percent of the staplers produced on monday were defective and 2 percent of the nondefective staplers were rejected by mistake. if 90 of the nondefective staplers were rejected, what was the number of staplers produced that day?

Answer 1

Because 12% of the staplers were defective or considered defective, we simply find 12% of a number that is equvalent to 90:

0.12x = 90

x = 750

750 staplers were produced
