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

### Instruction:
An alien invades Earth.  It abducts 200 people.  He returns 80% of the people abducted.  After that he takes 10 people to another planet.  He took the rest to his home planet.  How many people did he take to his home planet?

### Response:
 Aliwarudisha watu 200*.8=<<200*.8=160>>160
Hivyo alikuwa na watu 200-160=<<200-160=40>>40
Aliwachukua 10 kati yao kwenda sayari nyingine, hivyo aliwachukua 40-10=<<30=30>>30 kwenda sayari yake ya nyumbani.
