 <translate> Onum lake has 25 trout + 75 = 100 fish. Riddle Pond has 1 / 2 * 100 fish in Onum lake = 50 fish. Combined the three bodies of water have 100 fish + 50 fish + 75 fish = 225 fish. The average number of fish in the bodies of water is 225 fish / 3 = 75 fish.
Therefore, the answer is 75. <yor> Adágún Onum ní ẹja 25 + 75 = 100 ẹja. Riddle Pond ní 1 / 2 * 100 ẹja nínú adágún Onum = 50 ẹja. Tá a bá pa omi mẹ́tẹ̀ẹ̀ta pọ̀, ẹja 100 + ẹja 50 + ẹja 75 = ẹja 225.
