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, and Queen are preparing for the new school year and have been given books by their parents. Alannah has 20 more books than Beatrix. Queen has 1/5 times more books than Alannah. If Beatrix has 30 books, how many books do the three have together?

### 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.
