We count 35 heads and 94 legs among the chickens and rabbits in a farm. How many rabbits and how many chickens do we have?

public class ChickenAndRabbits

{

public static void main(String arga[])

{

int a=35;

int b=94;

int c=a*2;

int d=(b-c)/2;

System.out.println("RABBITS :"+d);

int e=a-d;

System.out.println("CHICKENS :+e);

}

}

OUTPUT

RABBITS 12

CHICKENS 23
