How many Chickens are there ?

A cow having 4 legs and a chicken having 2 leg.

No. of cows + No. of chickens=12

4(No. of cows) + 2 (No. of chickens) =28

solving these two equation,

No. of cows=2 and No. of chickens=10

Cows = 2 (2*4=8)
chicken = 10 (2*10=20)
8+20 = 28 legs

### 2 Cows and 10 Chickens

If the given question make this equation

``````4 ( x ) + 2 ( y ) = 28
``````

where
x = Number of Cows
y = Number of Chicken
then
Only there can be one possibility
if x = 2
and y = 10

``````4(2) + 2(10) = 28
``````
