~~~~~~~~~~~~~~~~
This problem is traditionally solved using proportions.
It is considered as very likelihood that the ratio of all turtles in the lake to the caught turtles in the first experiment
is the same as the ratio of the taught in the second experiment to the number of tagged among them:
 =  .
From the proportion,
x =  = 232.
ANSWER. The estimation is 232 turtles there are in the lake.

This problem is traditionally formulated for lakes, since with closed bodies of water the researchers are guaranteed
that both times they experiment with the same population.
