Chickens and rabbits

In the yard were chickens and rabbits. Together they had 27 heads and 86 legs. How many chickens and how many rabbits were in the yard?

Correct result:

chickens:  11
rabbits:  16

Solution:

a+b=27 2a+4b=86 a=11 b=16

a+b = 27
2•a+4•b=86

a+b = 27
2a+4b = 86

a = 11
b = 16

Calculated by our linear equations calculator.

We know that chicken has 2 legs and rabbit has 4. Assume that all heads are of chicken = 44*2 = 88. Now the difference between the total no. Of legs = 124-88 = 36. 36/2 =18 legs of Rabbits and 44-18 = 26 for chicken

Imagine all rabbits and chickens are well trained. We blow the whistle, all chickens and rabbits would retract one of their legs. 124 - 44 = 80. Then we blow the whistle again, they retract another leg. 80-44= 36. these remaining 36 legs belong to the rabbits which are standing with two legs (the other two are retracted). thus 36/2 = 18 rabbits. and the chickens are 44-18 = 26.
