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

### Instruction:
Mr. Maximilian is a dairy animal farmer and has 140 cows on his farm. Forty percent of the cows on his farm have a red spot, 25 percent of the cows without a red spot have a blue spot and the remaining cows do not have any spot. How many cows on the farm have no spot?

### Response:
 Ikiwa Bwana Maximilian ana ng'ombe 140 na asilimia 40 yao wana alama nyekundu, basi 40/100*140 = 56 ng'ombe wana alama nyekundu.
Idadi ya ng'ombe wasio na alama nyekundu ni 140-56 = <<140-56=84>>84.
Kati ya ng'ombe 84 wasio na alama nyekundu, asilimia 25 yao wana alama ya buluu, jumla ya ng'ombe 25/100*84 = 21.
Idadi ya ng'ombe wasio na alama yoyote ni 84-21 = <<84-21=63>>63.
