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

### Instruction:
 Mary anahesabu idadi ya minnows katika bwawa. Asilimia 40 ya minnows wana tumbo nyekundu, asilimia 30 wana tumbo kijani na wengine wana tumbo nyeupe. Ikiwa minnows 20 wana tumbo nyekundu, minnows wangapi wana tumbo nyeupe?


### Response:
 Idadi ya jumla ya minnows ni minnows 20 / 0.4 = <<20/0.4=50>>50 minnows
Idadi ya minnows kijani ni 30% * minnows 50 = <<30*.01*50=15>>15 minnows
Idadi ya minnows nyekundu au kijani ni minnows 15 + minnows 20 = <<15+20=35>>35 minnows
Idadi ya minnows nyeupe ni minnows 50 - minnows 35 = <<50-35=15>>15 minnows
