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

### Instruction:
The total age of the people in Kaydence's family is 200. If Kaydence's father is 60 years old, Kaydence's mother 2 years younger than Kaydence's father, Kaydence's brother 1/2 the age of Kaydence's father, and Kaydence's sister 40 years old, how old is Kaydence?

### Response:
 Baba wa Kaydence ana umri wa miaka 60, mama wa Kaydence ana umri wa miaka 60-2 = <<60-2=58>>58, na ndugu wa Kaydence ana umri wa 1/2 ya umri wa baba wa Kaydence.
Hivyo, baba wa Kaydence ana umri wa miaka 60, mama wa Kaydence ana umri wa miaka 58, na ndugu wa Kaydence ana umri wa miaka 60/2 = <<60/2=30>>30.
Jumla ya umri wa familia ni 200 miaka, na dada wa Kaydence ana umri wa miaka 40.
Kwa kuwa baba wa Kaydence ana umri wa miaka 60, mama wa Kaydence ana umri wa miaka 58, ndugu wa Kaydence ana umri wa miaka 30, na dada wa Kaydence ana umri wa miaka 40, jumla ya umri wa familia ni 60 + 58 + 30 + 40 = <<60+58+30+40=188>>188 miaka.
Kwa kuwa jumla ya umri wa familia ni 200 miaka na jumla ya umri wa familia ni 188 miaka, umri uliobaki ni 200 - 188 = <<200-188=12>>12 miaka.
Hivyo, Kaydence ana umri wa miaka 12.
