Answer 1

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 total number of goats?

Correct option is

20

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.
