ans:  cows 20 bird 15

Answer 2

Answer:  20 Cows & 15 Birds  

Step-by-step explanation: Let say number of cows = C

and number of Birds = B

Cow & Birds Have one Head Each

=> C + B = 35    Eq1

Cow has 4 legs & Birds has 2 Legs

=> 4C  + 2B  = 110   Eq2

Eq2 - 2 * Eq1

=> 2C  = 40

=> C = 20

   B = 15

20 Cows & 15 Birds
