Biologists collected a sample of 600 fish from West Okoboji Lake on May 1 and tagged each of them. When they returned on June 1, a new sample of 800 fish was collected and 10 of these had been previously tagged. Use this experiment to determine the approximate fish population of West Okoboji Lake.

The intuitive solution is by ratio assuming the population can be extrapolated by the sample, thus
population
=(600*(800/10)=48000.
