The ratio of the trout with tags that are caught and the total trout with tags is first calculated.
     r = 12 trout / 180 trout = 1/15
Then, we divide the number of trouts caught without tag by the value obtained above.
     N = (48 - 12) / (1/15) = 540
Then, we add the number obtained above and 180.
     T = 540 + 180 = 720
