Answer 2

There are 22 hens and 14 dogs

Step-by-step explanation:

Let the number of hens = x

Let the number of dogs= y

There are total 72 eyes

Therefore

$2x+2y=72\\\\\Rightarrow x+y= 36\\\\\Rightarrow x= 36-y-----(i)$

Now There are total 100 legs

$2x+4y=100\\\\\Rightarrow x+2y=50 -----(ii)$

Substitute the value of x from (i) in equation (ii) we get

$36-y+2y=50\\\\\Rightarrow y=50-36\\\\\Rightarrow y= 14$

Now substitute the value of y in (i)

$x=36-y= 36-14= 22$

Hence, there are 22 hens and 14 dogs
