There are 5n chickens and 20-3n rabbits, for n = 1,2,3,4,5 or 6.
12 chickens 4 rabbits
7 chickens and 11 Rabbits - 7 X 2 (feet per chicken) plus 11 X 4 (feet per rabbit) equals 58
Let's denote the number of chickens as C and the number of rabbits as R. We can write two equations based on the given information: C + R = 72 (total number of heads) and 2C + 4R = 200 (total number of feet). Solving these equations simultaneously, we find there are 50 chickens and 22 rabbits in the cage.
Suppose there are C chickens and R rabbits. Then Feet: 2*C + 4*R = 140 . . . . . (I) Heads: C + R = 50 . . . . . . . . (II) Equation (I) - Equation (II) gives: 2*C + 4*R - 2*C - 2*R = 140 - 2*50 or 2*R = 40 so that R = 20 and then, by (II), C + 20 = 50 so that C = 30. Answer: 20 rabbits and 30 chickens. This assumes, of course, that there are no headless chickens running around!
85 chickens
Suppose there are x chickens and y cows Then heads => x + y = 64 And Legs => 2x + 3y = 147 2*Heads: 2x +2y = 128 Subtract from Legs: 19 = y Substitute in Heads: x = 45 Answer: 45 chickens.
There are 42 chickens in the farm.
On a farm there are chickens and three-legged-cows. There are total of 49 heads and 130 legs. How many chickens are on the farm?
there are 80 goats and 20 chickens.
there are 36 horses and 23 chickens.........
They have their eyes on the sides of their heads, unlike we humans, who have our pointing forwards. As a typical prey animal, a rabbits eye position helps it to see all around without having to move. It can stay alert and watch its entire surroundings, without potentially giving its position to predators.
7 cows and 11 chickens. Cows have 4 legs. Chickens have 2 legs. (4 legs)(7 cows) + (2 legs)(11 chickens) = 50 legs. 7 cow heads = 11 chicken heads = 18 heads.
