30 Animals 74 Legs

A farmer has 30 animals consisting of chickens and cows. The animals have 74 legs in total. Find out the number of chickens and cows the farmer has.

Answer

23 Chickens and 7 Cows.

Let the number of chicken be X and number of cows be Y. Chickens have 2 and cows have 4 legs. Based on this, we can come up with 2 equations:

  • 2X + 4Y = 74
  • X + Y = 30

Solving for X and Y will give 23 and 7 respectively.
