### Instruction:
 Onum Lake ina samaki 25 zaidi ya Boast Pool. Boast Pool ina samaki 75. Riddle Pond ina nusu ya samaki kama Onum Lake. Wastani wa idadi ya samaki katika mabwawa yote matatu ni nini?


### Response:
 Jumla ya samaki katika Onum Lake ni 25+75=<<25+75=100>>100.
Jumla ya samaki katika Riddle Pond ni 100/2=<<100/2=50>>50.
Jumla ya samaki katika mabwawa yote matatu ni 100+75+50=<<100+75+50=225>>225.
Wastani wa idadi ya samaki katika mabwawa yote matatu ni 225/3=<<225/3=75>>75.
