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

### Instruction:
A tank contains 6000 liters of water, 2000 liters evaporated, and then 3500 liters were drained by Bob. How many liters are in the tank if it now rains for 30 minutes and every 10 minutes 350 liters of rain are added to the tank?

### Response:
 Kuna lita 6000 - 2000 = <<6000-2000=4000>>4000 za maji zilizobaki baada ya kuyeyuka kwa kwanza.
Kuna lita 4000 - 3500 = <<4000-3500=500>>500 za maji zilizobaki baada ya Bob kumwaga maji.
Ilinyesha kwa dakika 30, ambayo ni sawa na 30 dakika / 10 dakika = <<30/10=3>>3 mara ya kawaida ya dakika 10.
Hii inamaanisha jumla ya lita 3 * 350 = <<3*350=1050>>1050 za maji ziliongezwa kwenye tangi.
Jumla ya lita kwenye tangi sasa ni 500 + 1050 = <<500+1050=1550>>1550 lita.
