Farm2

The farm bred turkeys, geese, hens and chickens. Everything is 400. Turkeys and geese a hen are 150. No hen has more than one chicken, but some hens has no chick. Half of them is also a quarter of the chickens. When the turkey subtracting 15, we get 75. How many are turkeys, geese, hens? How many hens that has no chick?

Result

k =  90
h =  60
s =  250

Solution:


k+h+s = 400
k+h = 150
k-15=75

h+k+s = 400
h+k = 150
k = 90

h = 60
k = 90
s = 250
