Chickens and rabbits

In the yard were chickens and rabbits. They had 31 heads and 94 legs. How many chickens and how many rabbits was in the yard?


chickens:  15
rabbits:  16


Solution in text rabbits:=

a+b = 31

a+b = 31
2a+4b = 94

a = 15
b = 16

viju has 40 chickens and rabbits.  If in all there are 90 legs.  How many rabbits are there with viju??

35 chicken 5 rabbit

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.

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
