 
 <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. <ibo> Ọdọ mmiri Onum nwere 25 trout + 75 = 100 azụ. Riddle Pond nwere 1 / 2 * 100 azụ n'ọdọ mmiri Onum = azụ 50. E jikọtara mmiri atọ ahụ nwere azụ 100 + azụ 50 + azụ 75 = azụ 225. Nkezi ọnụ ọgụgụ azụ dị n'ime mmiri bụ azụ narị abụọ na iri abụọ na ise / atọ = azụ iri asaa na ise. N'ihi ya, azịza ya bụ 75.
