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

### Instruction:
In a house, there are 16 cats. Two of them are white, and 25% of them are black. The rest of the cats are grey. How many grey cats are in this house?

### Response:
 Kwenye nyumba hii, kuna paka weusi 16 * 25/100 = <<16*25/100=4>>4.
Idadi ya paka weupe na weusi kwenye nyumba hii ni 2 + 4 = <<2+4=6>>6.
Kama kuna paka 16 kwenye nyumba, basi kuna paka kijivu 16 - 6 = <<16-6=10>>10.
