Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
 Steve anamiliki duka la samaki la ziwa. Ana hisa ya samaki 200. Anauza samaki 50 na kwa sababu ya kuharibika kwa friji, theluthi moja ya samaki waliobaki wanaharibika. Hisa mpya ya samaki 200 inawasili. Ana samaki wangapi kwenye hisa sasa?


### Response:
 Alikuwa na samaki 200 - 50 = <<200-50=150>>150 waliobaki.
Samaki 150 * 1/3 = <<150*1/3=50>>50 wanaharibika.
Kwa hivyo sasa ana samaki 150 - 50 = <<150-50=100>>100.
Kisha anapata hisa mpya ya samaki 200 + 100 = <<200+100=300>>300 samaki.
Hivyo sasa ana hisa ya samaki 300.
