Given the total number of Legs and Head of Rabbits and Pigeons. The task is to calculate the number of Rabbits and Pigeons.
Input: Heads = 200, Legs = 540 Output: Rabbits = 70, Pigeons = 130 Input: Heads = 100, Legs = 300 Output: Rabbits = 50, Pigeons = 50
Let the total no. of Heads = 200 and Legs = 540.
Let the number of Head and Legs of Rabbits = X and that of Pigeons = Y.
X + Y = 200 ..equation 1 (no. of the heads of a rabbit and a pigeon = total no. of heads)
(As both of them has 1 head)
4X + 2Y = 540 …equation 2 (no. of the legs of the rabbit and a pigeon = total no. of legs)
(Rabbit have 4 legs and pigeons have 2 legs)
Now, solving equation 1 and 2 we get,
4X = 540 – 2Y
4X = 540 – 2 * (200 – X)
4X = 540 – 400 + 2X
2X = 140 => X = 70
X = 70 and Y = 130.
hence, Rabbits = 70 and Pigeons = 130
Below is the implementation of the above approach:
Rabbits = 50 Pigeons = 50
