Please next question

The Alchemist

Everyone knows that u can never devide any number by zero, in this proof a=1, b=1 and (a-b)=0. At the end of the proof both sides devided by (a-b). I think that is the mistake. 

A chicken farmer also has some cows for a total of 30 animals, and the animals have 74 legs in all.
How many chickens does the farmer have?

The Alchemist

I think a farmer has 25 chickens

Mars,

You are wrong because if there are 25 chickens then it'll be
25X2=50 chicken legs

74-50=24 cow legs

24 legs means 6 cows
so 25 chickens plus 6 cows total 31 animals.

Total number of animals in the question is 30 ea.

I think the answer is 23.
