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

### Instruction:
 Kulikuwa na wavuvi 20 katika ziwa ambao walitupa nyavu zao ili kukamata samaki. Ikiwa walikamata samaki 10000 jumla, na 19 kati yao walikamata samaki 400 kila mmoja na nyavu zao, hesabu idadi ya samaki aliyekamatwa na mvuvi wa ishirini.


### Response:
 Wavuvi 19 walikamata 19*400 = <<19*400=7600>>7600 samaki.
Jumla ya samaki walio kamata ni 10000, maana yake mvuvi wa ishirini alikamata 10000-7600 = <<10000-7600=2400>>2400 samaki peke yake.
