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 most appropriate option:	A) 400	B) 625	C) 1250	D) 2500	E) 10 000

Rationale: "if x is total number of fish in the pond : 4 = 50 / x * 100 = > x = 1250 so answer is c"
Answer: C
