Question

A farmer has some hens and goats he count total of 60 eyes and 86 feet b/w them then how meny hens dose have

Answer 1

Answer:

17 hens

Step-by-step explanation:

hens and goats both have 2 eyes so 60/2 shows the total number of animals in the farm which is 30

let the number of hens be h and the number of goats be (30-h) because the number of hens and goats make 30 altogether

hens have 2 legs so it is 2h; goats have 4 legs so it is 4(30-h)

adding them up makes up the total amount of legs

2h + 4(30-h) = 86

2h + 120 - 4h = 86

-2h = -34

h = 17
