In a certain pond, 60 fish were caught, tagged, and returned to the pond. A few days later, 60 fish were caught again, of which 2 were found to have been tagged. If the percent of tagged fish in the second catch approximates the percent of tagged fish in the pond, what`s the approximate number of fish in the pond? Pick
A) 400	B) 625	C) 1818	D) 2500	E) 10 000
The percent of tagged fish in the second catch is 2/60*100 = 3.33%.   We are told that 3.33% approximates the percent of tagged fish in the pond. Since there are 60 tagged fish, then we have 0.033x = 60 --&gt; x = 1,818.   Answer: 1818.
