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

### Instruction:
 Bella, Monica, na Rachel ni marafiki ambao wanapenda vito vya mapambo. Bella ana vipuli vya masikioni 10, ambavyo ni asilimia 25 ya vipuli vya Monica, na Monica ana vipuli mara mbili ya vipuli vya Rachel. Marafiki hawa wana vipuli vingapi vyote?


### Response:
 Kwa kuwa Bella ana 100% / 25% = 4 mara chache vipuli kuliko Monica, hii inamaanisha kuwa Monica ana vipuli 10 * 4 = <<10*4=40>>40.
Rachel ana vipuli mara mbili chache kuliko Monica, ambayo inamaanisha ana vipuli 40 / 2 = <<40/2=20>>20.
Hivyo marafiki hawa watatu wana vipuli 20 + 40 + 10 = <<20+40+10=70>>70 jumla.
