Question

A farmer has some cocks and goats. If they all have 90 heads and 224 legs, how much is the goats?​

Answer 1

Answer:

22 goats

Step-by-step explanation:

let number of cocks be x and number of goats be y

according to the question,

x+y= 90

2 x + 4 y = 224  [ as cocks have 2 legs and goat as 4 legs ]

2(x+y=90)

2 x + 4 y = 224

2 x + 2 y = 180

by subtracting we get 2 y = 44

so, y = 22

therefore, number goats is 22

Answer 2

Answer:

22

Step-by-step explanation:

let no. of goats =x

" " hens=y

They all have 90 heads all together

So, x+y=90

A goat has 4 legs while a hen has 2

So, no of legs = 4x+2y=224

We simplify the equation to get

2x + y =112

x+x+y=112

as we know x+y = 90

x+90=112

x=22

Hope this will help you !
