### Instruction:
 Uncle Ben ana kuku 440 kwenye shamba lake. Kati yao, 39 ni jogoo na wengine ni kuku. Kuku 15 hawatowi mayai, na wengine wanatowa. Kama kila kuku anayetowa mayai anatowa mayai 3, Uncle Ben atakuwa na mayai mangapi?


### Response:
 Uncle Ben ana kuku 440 - 39 = <<440-39=401>>401.
Uncle Ben ana kuku 401 - 15 = 386 ambao wanatowa mayai.
Kila kuku anayetowa mayai anatowa mayai 3 * 386 = <<3*386=1158>>1158.
