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

### Instruction:
Jenny is older than Charlie by five years, while Charlie is older than Bobby by three years. How old will Charlie be when Jenny becomes twice as old as Bobby?

### Response:
 Jenny ni mkubwa kuliko Charlie kwa miaka 5 ambaye ni mkubwa kuliko Bobby kwa miaka 3, hivyo Jenny ni mkubwa kuliko Bobby kwa miaka 5+3 = <<8=8>>8.
Jenny atakuwa mara mbili ya umri wa Bobby wakati Bobby atakuwa na miaka 8*2 = <<8*2=16>>16.
Jenny ana miaka 16-5 = <<16-5=11>>11.
Jenny atakuwa na miaka 11*2 = <<11*2=22>>22 wakati Charlie atakuwa na miaka 16.
Jenny ni mkubwa kuliko Charlie kwa miaka 11.
Hivyo wakati Jenny atakuwa na miaka 22, Charlie atakuwa na miaka 22-11 = <<22-11=11>>11.
