Question 1094481: Farmer Del has 40 more chickens than cows on his farm. He also has 10 fewer pigs than cows and 20 fewer sheep than chickens. He also has 4 horses. If Farmer Del has a total of 110 animals on his farm, how many of each kind does he have? Found 2 solutions by ikleyn, MathTherapy:Answer by ikleyn(52794) (Show Source):
Let the number of cows be x.
Then the number of chickens is (x+40),
the number of pigs is (x-10),
the number of sheep is ((x+40) - 20) = (x+20),
The number of horses is 4.
Altogether
cows + chicken + pigs + sheep + horses = 110 ====>
x + (x+40) + (x-10) + (x+20) + 4 = 110 ====>
4x + 40 - 10 +20 + 4 = 110 ====>
4x + 54 = 110 ====> 4x = 110-54 = 56 ====> x = = 14.
So, farmer Del has 14 cows.
