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

### Instruction:
 Kuna magari 4 katika treni na kila gari lina viti 25. Ikiwa kila gari linaweza kuchukua abiria 10 zaidi, abiria wangapi wangejaza treni 3?


### Response:
 Ikiwa kila gari lingekuwa na viti vingine 10, kila gari lingekuwa na viti 25 + 10 = 35.
Magari 4 katika treni na viti 35 kila moja katika treni ni 4 * 35 = <<4*35=140>>140 viti.
Treni 3 zenye viti 140 kila moja katika treni ni 3 * 140 = 420 viti.
