In a certain pond, 100 fish were caught, tagged, and returned to the pond. A few days later, 100 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 is the approximate number of fish in the pond?
Choose the correct choice from the following answers:	A) 400	B) 625	C) 1,250	D) 2,500	E) 10,000
total fish = x   percentage of second catch = (2/100)*100= 
<gadget id="calculator">(2/100)*100</gadget>
<output>2</output>
2%   so, x * 2%= 50   x = 2500 ans. 2,500
<result>D</result>
