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

### Instruction:
Yeon has three times as many watermelon seeds as Gwi. Gwi has 40 more watermelon seeds than Bom. If Bom has 300 watermelon seeds, how many seeds do they have together?

### Response:
 Ikiwa Bom ana mbegu 300, basi Gwi ana mbegu 300+40 = <<300+40=340>>340 za tikiti maji.
Pamoja, Bom na Gwi wana 340+300 = <<340+300=640>>640 mbegu za tikiti maji.
Idadi ya mbegu za tikiti maji za Yeon ni mara tatu ya idadi ya mbegu za Gwi, maana Yeon ana 3*340 = <<3*340=1020>>1020 mbegu za tikiti maji.
Idadi ya mbegu za Yeon ni pia 1020-640 = <<1020-640=380>>380 zaidi ya idadi ya mbegu walizo nazo Bom na Gwi pamoja.
Pamoja, marafiki watatu wana 1020+640 = <<1020+640=1660>>1660 mbegu za tikiti maji.
