Peter caught a total of 8 fish. The three largest fish weighed 35 kg, meaning the average weight of each large fish was about 11.67 kg. The three smallest fish weighed 25 kg, equating to an average weight of 8.33 kg per small fish. By adding the weights of the largest and smallest fish, we can find the total weight of all the fish caught, which is 60 kg. Since the total weight of the fish caught is 100 kg, the weight of the remaining two fish totals 40 kg. Those two fish each have an average weight of 20 kg.
