What's there to disagree with?

This is a rather straight forward ratio problem.

1. 50 fish tagged

2. 2 out of the 50 fish caught were tagged thus 2/50

2/50=50/x

thus, x=1250

Think of the analogy: 2 fish is to 50 Fish as 50 fish is to ...?

You've tagged 50 fish and you need to find what that comprises as a percentage of the total fish population - we have that information with the ratio of the second catch.
