In a forest many hens and many Cow were live If total number of legs were180 and total numer of eyes is120 including both animal.So,how many hens and Cow were live in a forest???

• 2h+2c=120(since cow and hen each have a pair of eyes)
  h+c=60 ---eq1
  2h+4c=180
  h+2c=90 --eq2
  solve eq1 & eq2
  we get no of hens=30 and no of cows=30
