<human>:  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?
<bot>: How many cows have red spots? ** If Mr. Maximilian has 140 cows and 40% of them have red spots, then 40/100*140 = <<140*40/100=56>>56 cows have red spots.
How many cows have no red spot? ** The number of cows with no red spot is 140-56 = <<140-56=84>>84 cows.
How many cows have a blue spot? ** Out of the 84 cows without a red spot, 25% of them have a blue spot, a total of 25/100*84 = <<25/100*84=21>>21 cows.
How many cows have no spot? ** The number of cows without any spot is 84-21 =<<84-21=63>>63 animals.
