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 61 horses and 10 chickens on the farm.
there are 36 horses and 23 chickens.........
There are 42 chickens in the farm.
85 chickens
50 horses and 10 chickens
If all were horses there would be 428 legs. The shortfall of 36 legs represents 18 chickens so there are 89 horses.
67
If all were horses there would be 4 x 61 ie 244 legs. There is a shortfall of 50 legs ie 25 less four-legged creatures, so there are 36 horses and 25 chickens, giving 144 + 50 legs
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.
On this farm there would be a total of 18 cows. There would also be 18 chickens, combining to make 36 heads and 104 legs.
94 three legged cows and 25 chickens.
