A farmer has some hens and some goats. If the total number of animal heads is 80 and the total number of animal feet is 200, what is the tolal number of goats?
20
Explanation:
As per fact that hens and goats each have one head and 2 legs and 4 legs respectively
let no of hen = x, no of goats = y
x + y = 80
2x + 4y = 200
By solving x = 60, y = 20
