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

### Instruction:
 Arman ni mara sita mkubwa kuliko dada yake. Dada yake ana miaka 2 miaka minne iliyopita. Baada ya miaka mingapi umri wa Arman utakuwa miaka 40?


### Response:
 Dada yake Arman ana miaka 4 + 2 = <<4+2=6>>6 sasa.
Hivyo, Arman ana miaka 6 x 6 = <<6*6=36>>36.
Hivyo, umri wa Arman utakuwa miaka 40 baada ya miaka 40 - 36 = <<40-36=4>>4.
