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

### Instruction:
 Ravi ana sarafu kadhaa. Ana sarafu 2 zaidi ya robo na sarafu 4 zaidi ya robo. Ikiwa ana robo 6, anayo pesa kiasi gani?


### Response:
 Ravi ana robo 6 + 2 = <<6+2=8>>8.
Ana pia robo 8 + 4 = <<8+4=12>>12.
Ruba ni sawa na senti 5 hivyo robo za Ravi ni sawa na 6 x 5 = <<6*5=30>>30 senti.
Robo ni sawa na senti 25 hivyo robo za Ravi ni sawa na 8 x 25 = <<8*25=200>>200 senti.
Daimu ni sawa na senti 10 hivyo daimu za Ravi ni sawa na 12 x 10 = <<12*10=120>>120 senti.
Hivyo, Ravi ana jumla ya 30 + 200 + 120 = <<30+200+120=350>>350 senti.
