**#Puzzle :**

A farmer had some chickens and some cows.

She counted 40 heads and 126 legs.

*How many chickens and how many cows did she have?*

##### Show answer

**Answer : 17 Chickens and 23 Cows**

**Explanation:**

C = #chickens

M = #cows

40 = C + M, 40 – M = C

126 = 2C + 4M

126 = 2(40 – M) + 4M

126 – 80 = 4M – 2M

46 = 2M

**23 = M**

40 – 23 = C

**17 = C**

**So C= Chicken 17 and M= Cows = 23Ā **
