Dear,
I'm almost able to resolve this one but I have a doubt with the result.
Here come the question,
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 90 of the non defective staplers were rejected, what was the number of staplers produced that day?
4000 ; 4200 ; 4500 ; 4800 : 5000
At first I did the obvious mistake of considering that 90 staplers are equally to 2% of the researched amount.
After looking at it again, I realized my mistake and calculated the following.
90 represent (0.9*0.02 --> 0.018) 1.8% of the researched amount. This will imply that the final amount is closed to 5600. Which is a bit far of the 5000 given as the right answer.
Can anybody tell me if I'm doing something wrong? if yes, why
?
Many thanks
Lukas
