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

### Instruction:
 Betty ana vitabu 20, na dada yake ana vitabu 1/4 zaidi ya Betty. Jumla ya vitabu wawili hao ni vingapi?


### Response:
 Dada yake Betty ana vitabu 1/4 zaidi ya Betty, ambayo inamaanisha ana vitabu 20*1/4 = <<20*1/4=5>>5 zaidi.
Jumla ya vitabu ambavyo dada yake Betty ana ni vitabu 20+5 = <<20+5=25>>25.
Pamoja, wawili hao wana vitabu 25+20 = <<25+20=45>>45.
