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

### Instruction:
 Alannah, Beatrix, na Queen wanajiandaa kwa mwaka mpya wa shule na wamepewa vitabu na wazazi wao. Alannah ana vitabu 20 zaidi ya Beatrix. Queen ana vitabu 1/5 mara zaidi ya Alannah. Ikiwa Beatrix ana vitabu 30, watatu hao wana vitabu vingapi pamoja?


### Response:
 Ikiwa Beatrix ana vitabu 30, Alannah ana vitabu 30 + 20 = <<30+20=50>>50.
Queen ana 1/5 * 50 = <<1/5*50=10>>10 zaidi ya Alannah.
Pamoja, Queen na Alannah wana vitabu 10 + 50 = <<10+50=60>>60.
Beatrix akiwa na vitabu 30, watatu hao wana vitabu vya Beatrix 30 + vitabu vya Queen 60 + vitabu vya Alannah 50 = <<30+60+50=140>>140 pamoja.
