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

### Instruction:
 Ken alikuwa na madaftari hamsini, na alitaka kugawana baadhi yao na marafiki zake wawili, Manny na Nilo. Ken alimpa Manny madaftari kumi na madaftari kumi zaidi kwa Nilo kuliko alivyompa Manny. Alihifadhi madaftari mengine. Ken alihifadhi madaftari mangapi?


### Response:
 Nilo alipokea 10 + 10 = <<10+10=20>>20.
Hivyo, Ken alitoa jumla ya 10 + 20 = <<10+20=30>>30.
Hivyo, Ken alihifadhi madaftari 50 - 30 = <<50-30=20>>20.
