At a certain factory, 10 percent of the staplers produced on Monday were defective and 2 percent of the non-defective staplers were rejected by mistake. If 72 of the non-defective staplers were rejected, what was the number of staplers produced that day?
Correct answer: A
Explanation
We're told that 10% of staplers in a factory are defective.
X = Total staplers
0.1X = defective staplers
0.9X = normal staplers
Next, we're told that 2% of the normal staplers were rejected by mistake and that this = 72 staplers.
0.9X(0.02) = 72
0.018X = 72
18X = 72,000
X = 4,000
Final Answer:
A
