Total no of animals are..90

let no of hens be x

then goats = 90-x

then

no of legs = 248 = 2x+4(90-x)

2x+360-4x = 248

360-248 = 2x

x = 112/2 = 56

then

no of goats = 90-56 = 74

No of goats = 34

No of hens = 56

Step-by-step explanation:

Let hens = H, goats = G

According to the question,

H + G = 90 ...(i)

2H + 40 = 248 ...(ii)

On multiplying Eq. i) by 2 and subtracting from Eq. (ii), we get

by solving 1 and 2 we get

-2G = -68

G = 34
