option (3) 200 is the correct option because;
we shall consider the total number of fishes be 'x' and 80percent of them are tagged . In the second part of the question,40 of total fishes caught are tagged which means that about 40 percent of total fishes are tagged as total caught fishes are 100. So , 40percent of 'x' is 80 , which gives the total number of fishes to be 200.
Hope you understood;)
