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

### Instruction:
A bear is preparing to hibernate for the winter and needs to gain 1000 pounds. At the end of summer, the bear feasts on berries and small woodland animals. During autumn, it devours acorns and salmon. It gained a fifth of the weight it needed from berries during summer, and during autumn, it gained twice that amount from acorns. Salmon made up half of the remaining weight it had needed to gain. How many pounds did it gain eating small animals?

### Response:
 Dubu alipata pauni 1000 / 5 = <<1000/5=200>>200 kutoka kwa matunda ya kunde.
Alipata pauni 2 * 200 = <<2*200=400>>400 kutoka kwa mizizi ya mwaloni.
Bado ilihitaji pauni 1000 - 200 - 400 = <<1000-200-400=400>>400.
Hivyo, ilipata pauni 400 / 2 = <<400/2=200>>200 kutoka kwa samaki wa kisalmoni.
Hivyo, ilipata pauni 400 - 200 = <<400-200=200>>200 kutoka kwa wanyama wadogo.
