In a certain pond, 50 fish were caught, tagged, and returned to the pond. A few days later, 50 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?	Choose the correct choice from the following choices:  A) 400  B) 625  C) 1250  D) 2500  E) 10 000
If x is total number of fish in the pond :   4 = 50/x * 100   =&gt; x = 1250   So answer is 1250
